-fno-plt breaks Left 4 Dead 2 / Portal 2 -vulkan
Gentoo Linux 5.15-pf5+
gcc version 12.0.0 20211218 (experimental) (Gentoo 12.0.0_pre9999 p2, commit 31048012db98f5ec9c2ba537bfd850374bdd771f)

I haven't bisected this yet, but building mesa with the -fno-plt gcc flag results in Left 4 Dead 2 and Portal 2 crashing after attempting to launch if the -vulkan command line parameter is used to enable the vulkan render. CSGO will launch fine using -vulkan.
