The using the link time optimisation flag is not an officially supported way to
build mesa.

FYI:

ppl from Phoronix forums located the cause of the problem: gen_matypes.c is
passed to the compiler in order to generate assembly code in text form
(compiler switch: -S), but with -flto GCC doesn't output any code nor data
because that is postponed to link time. In such case gcc -S -flto generates a
file with empty .text and .data sections.

This isn't a GCC bug. Passing -ffat-lto-objects solves issue for me so maybe if
compile passes -S together with -flto then the config should imply
-ffat-lto-objects ?

Bug ID: 96550
   Summary: 12.0.0-rc3: mesa_dri_drivers.so linking fails with:
relocation R_X86_64_32S against `V4F_COUNT' can not be
used when making a shared object
   Product: Mesa
   Version: git
  Hardware: x86-64 (AMD64)

I'm trying to build 12.0.0-rc3 in cross-compile environment.
Build fails at mesa_dri_drivers.so linking with following error:

11.2.2 builds perfectly in the same environment.
