Hi guys,
Another patch for multiarch support. The need for this was discovered when
trying to bootstrap a cross-toolchain against a multiarchified
eglibc-source.
We should explicitly prepend the appropriate multiarch paths to our library
search path. These would be picked up later on anyway in the case of a
native build, but for, e.g., bootstrapping a cross-toolchain the needed
multiarch paths aren't going to be found in ld.so.conf.
