# Assembler & linker features

+# 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
