Platforms like powerpc64le have different variants of the same target.
Perl guesses that the target should be called powerpc64le-linux, while
TARGET_ARCH think it is called ppc64le-linux. If we use TARGET_ARCH
for perl-native on powerpc64le this build will fail since the
post-install rm command won't reference and existing file.
We know that there is only one arch existing per build, so use a
wildcard for finding the path instead of trying to guess the correct
architecture name.
