[Buildroot] [git commit] autotools-package: also handle pre-installed external toolchain in .la fixup

commit: http://git.buildroot.net/buildroot/commit/?id=8c488211385b4f46cb290fbdc79bdb1912c1d1be
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The .la fixup handling looks for paths starting with /usr and assumes
that they are missing the installation prefix (i.e. $(STAGING_DIR)). It
already handles the cases that $(STAGING_DIR) itself and $(BASE_DIR)
are under /usr, but it does not yet handle the case that a
pre-installed external toolchain is under /usr (and tracks that fact
in some .la file). For instance, if you use buildroot to generate a
toolchain with HOST_DIR=/usr/local/some_path, this problem will occur.

Fix this in the same way as $(STAGING_DIR) and $(BASE_DIR), but in
addition check that TOOLCHAIN_EXTERNAL_INSTALL_DIR is non-empty. For
internal toolchains, it is empty and the sed expression would fail.
