This patch fixes libexpat detection for gdb-native and
gdb-cross static builds.
For gdb-native build configure should not touch system
/usr/{lib,include} directories while looking for libexpat.
To fix this we pass --without-libexpat-prefix flag
to configure script.
For gdb-cross build configure is allowed to investigate
system /usr/{lib,include} directories, but it does not
hurt to disable this behavior. In this case configure
falls back to -lexpat, which works as expected.
