 configure: Make sure we try all possible linkers

 Previously if we had both ld.lld and ld.gold installed but a gcc which
 didn't support -fuse-ld=lld we would fail when trying ld.lld and fall
 immediately back to plain ld. Now we will try ld.gold as well. This was
 brought to light by #14280, where using ld.bfd resulted in a broken
 stage2 compiler.

 Test Plan: Configure
