#
# We explictly remove 'liblzo2.la' because some packages that depend
# on liblzo2 use libtool. If libtool finds a '*.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
# '-llzo2' to '/usr/lib/liblzo2.so'. 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.
