guix: disable libsanitizer in Linux GCC build #33780

1. 
   fanquake commented at 5:33 pm on November 4, 2025: member

   This causes issues when building against newer glibcs (i.e 2.42), and isn’t needed in any case.

   0../../../../gcc-14.3.0/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:483:31: error: invalid application of ‘sizeof’ to incomplete type ‘__sanitizer::termio’
   1  483 |   unsigned struct_termio_sz = sizeof(struct termio);
   2      |                               ^~~~~~~~~~~~~~~~~~~~~
   

   Extracted from #25573.
