PATCH: xfsprogs-1.3.1/configure.in - Cross Compilation

[Grant Erickson <gerickso@xxxxxxxxxxx>]

Below is a patch to allow the xfsprogs-1.3.1/configure script to work
correctly (at least mostly correctly) when cross-compiling from
sparc-sun-solaris to powerpc-linux-gnu. The idea and code is
lifted, more or less, wholesale from e2fsprogs-1.22:
