[Bug lto/41376] New: collect2 (and maybe lto1) do not handle static libraries

[rguenth at gcc dot gnu dot org]

collect2 does not handle static libraries to maybe_run_lto_and_relink so it
doesn't get a chance to optimize using its content.  This for example means
that when bootstrapping with BOOT_CFLAGS=-flto libbackend.a does not benefit
from lto.
