Hi,

The ‘fmod’ symbol is missing from the i686-linux libm.a, but it’s
available in the x86_64 libm-2.39.a:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix shell --pure -s x86_64-linux gcc-toolchain <at> 11{,:static} -- gcc -Wall -O2 fmod.c -lm -static
$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 3.2.0, not stripped

$ ./pre-inst-env guix shell --pure -s i686-linux gcc-toolchain <at> 11{,:static} -- gcc -Wall -O2 fmod.c -lm -static
ld: /tmp/ccvt0V2Q.o: in function `main':
fmod.c:(.text.startup+0x3c): undefined reference to `fmod'
collect2: error: ld returned 1 exit status
$ cat fmod.c
#include <math.h>
#include <stdlib.h>

int main (int argc, char *argv[])
{
  return fmod (atof (argv[1]), atof (argv[2]));
}
--8<---------------cut here---------------end--------------->8---

I’m not sure why that is the case; i686 seems to be the only one with
that problem.
