Michael Forney 0867cdf300 Fix LINUX_ARCH for aarch64-* TARGET 
'aarch64' is converted to 'arm64' in the TARGET_ARCH_MANGLED assignment,
but then LINUX_ARCH is set the first to the first linux arch which
appears in TARGET_ARCH_MANGLED. Since 'arm' is a substring of 'arm64'
and appears ahead of 'arm64' in sorted order, it gets chosen
incorrectly.

To fix this, use 'lastword' instead of 'firstword'. This should work for
all current linux architectures, but is still not perfect in the
theoretical case where the substring match is not rooted at the
beginning of TARGET_ARCH_MANGLED. So, also replace 'findstring' with an
'if' and 'filter'.
