tcc: Explicitly require -l<lib> for libraries
...
Previously it was possible to specify e.g. -q<lib> and still link with
lib. Avoid such behaviour by checking for '-l' instead of '-l.'

tcc: Draft suppoprt for -MD/-MF options
...
In build systems, this is used to automatically collect target
dependencies, e.g.
---- 8< (hello.c) ----
#include "hello.h"
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
$ tcc -MD -c hello.c # -> hello.o, hello.d
$ cat hello.d
hello.o : \
hello.c \
hello.h \
/usr/include/stdio.h \
/usr/include/features.h \
/usr/include/bits/predefs.h \
/usr/include/sys/cdefs.h \
/usr/include/bits/wordsize.h \
/usr/include/gnu/stubs.h \
/usr/include/bits/wordsize.h \
/usr/include/gnu/stubs-32.h \
/home/kirr/local/tcc/lib/tcc/include/stddef.h \
/usr/include/bits/types.h \
/usr/include/bits/wordsize.h \
/usr/include/bits/typesizes.h \
/usr/include/libio.h \
/usr/include/_G_config.h \
/usr/include/wchar.h \
/home/kirr/local/tcc/lib/tcc/include/stdarg.h \
/usr/include/bits/stdio_lim.h \
/usr/include/bits/sys_errlist.h \
NOTE: gcc supports -MD only for .c -> .o, but in tcc, we generate
dependencies for whatever action is being taken. E.g. for .c -> exe, the
result will be:
$ tcc -MD -o hello hello.c # -> hello, hello.d
hello: \
/usr/lib/crt1.o \
/usr/lib/crti.o \
hello.c \
hello.h \
/usr/include/stdio.h \
/usr/include/features.h \
/usr/include/bits/predefs.h \
/usr/include/sys/cdefs.h \
/usr/include/bits/wordsize.h \
/usr/include/gnu/stubs.h \
/usr/include/bits/wordsize.h \
/usr/include/gnu/stubs-32.h \
/home/kirr/local/tcc/lib/tcc/include/stddef.h \

So tcc dependency generator is a bit more clever than one used in gcc :)
Also, I've updated TODO and Changelog (in not-yet-released section).
v2:
(Taking inputs from grischka and me myself)
- put code to generate deps file into a function.
- used tcc_fileextension() instead of open-coding
- generate deps only when compilation/preprocessing was successful
v3:
- use pstrcpy instead of snprintf(buf, sizeof(buf), "%s", ...)

tcc: Refactor "compute default outfile name" into libtcc function
...
Since for upcoming -MD support default _compile_ output file be needed
even when preprocesssing (tcc -E), let's move this code out of one
particular condition block into a common function, so that we could use
it in deps generation code too.
v2:
- As suggested by grischka, moved into libtcc function instead of always
computing near start of main()
- There is a FIXME about how to return result - I don't want to bother
callers with allocating temp buffers, not I think it will be a good
idea to hook default_target to TCCState. Clearly, I'm to used to
things like std::string and python's str...

Add input files/libs and reloc_output switch to TCCState
...
files[0], and reloc_outpu will be needed for (upcoming in the next
patch) "compute default outfile name" refactored into libtcc function.
Also, since for symmetry and from libification point of view, it makes
some sense to also put all information about what was given as input to
compilation into TCCState, let's not only put files[0], but all
files and all libraries given explicitely by user.
One point: I've used bitfield for reloc_output & trimmed down
output_type to 8 bits so that TCCState stays the same in size, and also
access to output_type is (hopefully) is not slower.
By the way -- as of today, sizeof(TCCState) on i686-pc-linux-gnu is 2884
bytes...

Recognize -Wl,-Bsymbolic
...
Without -Bsymbolic, a symbol/function in a *.so can be overridden
by a symbol/function in the main module.
That is the default search order, but not supported by tcc.
With -Bsymbolic, the linker tries to resolve a symbol/function in
the current module first.
The loader in tcc implements this search order.
We do not distinguish -Bsymbolic and -Bsymbolic-function
