=sys-libs/efivar-38 surprisingly crashes the linker (GNU ld) when linking libefivar.so. Observed and reproducible on amd64, arm64, and ppc64. The issue does NOT affect =sys-libs/efivar-37 on any arch. emerge --info is from arm64, but the issue seems to be arch-independent. Using =sys-devel/binutils-2.37_p1-r1.

Please try with simpler CFLAGS.
Adding toolchain.
(In reply to Mike Gilbert from comment #1) > Please try with simpler CFLAGS. Oops, looks like it's an LTO thing. Toggling -flto fixes it. Could that be stripped with flag-o-matic please?
(In reply to matoro from comment #3) > Oops, looks like it's an LTO thing. Toggling -flto fixes it. Sounds like a binutils bug.
