-# During stage 2, ld is actually gcc/collect-ld, which is a small script to
-# discern between when to use prev-ld/ld-new and when to use ld/ld-new.
-# However when ld-new is first executed from the build tree, libtool will
-# relink it as .libs/lt-ld-new, so that it can give it an RPATH that refers
-# to the build tree.  While doing this we need to use the previous-stage
-# linker, or we have an infinite loop.  The presence of a shell script as
-# ld/ld-new, and the fact that the script *uses ld itself*, is what confuses
-# the gcc/collect-ld script.  So we need to know how libtool works, or
