Emerging pipewire-1.4.1 failed with thin-LTO enabled in /etc/portage/make.conf. I observed that ninja tried to use ld.bfd even though I added '-fuse-ld=lld' into LDFLAGS. It was built without a problem when gcc toolchain was used. Note that the bug might not be confined to pipewire: similar errors have been observed some other packages using meson/ninja such as zstd. Reproducible: Always Steps to Reproduce: 1. Add ~amd64 flag to pipewire 2.

Does adding LD="ld.lld" to make.conf help?
