# We explictly remove 'libfoo.la' because some packages that depend on
# these libraries use libtool. If libtool finds a 'libfoo.la' file for
# a library, it uses the value of 'libdir=<dir>' it finds. In our
# case, since '--prefix=/usr' this value is '/usr/lib'. It then
# resolves '-lfoo'. In a cross-compilation environment, this is likely
# to be neither the right architecture nor the right version to link
# against. In short, we lose.
#
# We could also handle this by removing DESTDIR and setting the prefix
# to $(ResultDirectory); however, that results in libtool hard-coding
# $(ResultDirectory) as the RPATH in the linked executables which is
# NOT what we want either. We lose again.
#
# By removing the '*.la' file, we win by ensuring neither a misdirected
# link nor an RPATH.
