Two remarks:
1. Only gcc-16 is alive, 15 and 11 is unbind and can be skipt
2. As soon as we switched gcc to LLD instead of BFD, gcc will use LLD for
everything. I saw similar error recently on i386 VM when tried make test
at ffmpeg, and it exists on both ffmpeg-8 and ffmpeg-9, the error was:
ld: error: relocation R_386_32 cannot be used against local symbol; recompile
with -fPIC
>>> defined in libavcodec/libavcodec.a(xvididct.o)
>>> referenced by x86inc.asm:1508 (src//libavutil/x86/x86inc.asm:1508)
>>> xvididct.o:(.text+0x1ac) in archive libavcodec/libavcodec.a
So, I a bit afraid to switch gcc generally to lld in 386 without full bulk
which confirms that it is safe.
