Subject: external-csl-toolchain: support ia32

Unfortunately, the CSL ia32 toolchain has non-prefixed binaries in its bindir
(e.g. gcc, ld). To avoid this messing up our build, we avoid adding this
bindir to our PATH, and instead add symlinks to the prefixed binaries to our
staging toolchain bindir.
