I spent some time investigating this issue but the problem is that mesa try to
link with libcoregrind-<arch>-linux.a to build libgbm.so. But even by hacking
the valgrind build system, the build is still failing.

I tried with several toolchain (glibc and uclibc).

Out of curiosity, what's your use case that require valgrind in mesa3d ?

Note: The valgrind support is enabled in archlinux and fedora



But no problem on their side ?

Any idea ? otherwise we have to revert this patch because the build is still
failing in the autobuilder.

Best regards,
