Well, this is still not going to work for me. On Linux bi-arch systems, 64-bit
libraries are found in /lib64 and /usr/lib64. This line is not going to help
about it:
-e's|tcc_add_library_path(s, CONFIG_SYSROOT
"/lib");|tcc_add_library_path(s, "${stdenv.glibc}/lib");|g;

I can reproduce it like this:

#include <stdlib.h>

Indeed, the problem was already at configuration time:
checking whether nextafter can be used without linking with libm... no
checking whether nextafter can be used with libm... no
Fixing it through the patch below.
