Hello, please see v2 of the tc-ld-force-bfd() patch below.

v2 changes: only calls tc-ld-force-bfd from tc-ld-disable-gold if
the gold linker is active.

With this change ebuilds that require both ld.gold & ld.lld to be
disabled will need to be updated to use tc-ld-force-bfd.

Subject: [PATCH] toolchain-funcs.eclass: new function tc-ld-force-bfd()

No functions currently force ld.bfd usage when ld.lld is active.
This function forces ld.bfd when either ld.gold or ld.lld is active.
tc-ld-disable-gold() now calls this new function
 only if ld.gold is active.
