MIPS: Netlogic: Specify architecture CFLAGS
Use -march=xlr if available, otherwise fallback to mips64. This allows
us to support compilation with MIPS toolchains which are not customized
for XLR.
[ralf@linux-mips.org: And more importantly it works around a gas bug in
binutils 2.21 which otherwise may result in an assertion failure building
arch/mips/kernel/genex.S. See
http://sourceware.org/bugzilla/show_bug.cgi?id=12915 for details.]
