nspr failed to build on x86_64 board(e.g., qemux86-64):
x86_64-poky-linux-gcc -m64 ... -m32 ...
...
fatal error: gnu/stubs-32.h: No such file or directory
This is because there are both '-m64' and '-m32' in gcc's options, and
the later one is used, but what we need is '-m64' since it is x86_64,
this is caused by an incorrect logic in configure.in, we should assume
that the pkg uses 64bit when target_cpu is x86_64 (it has two options:
--enable-n32 and --enable-64bit, both of them are not set by default),
we only can assume that the pkg uses 32bit when USE_N32 is set. But
what it did was that assumed 32bit when target_cpu was x86_64 unless
--enable-64bit was set, this seems unreasonable and caused the "gcc -m64
-m32" error.
Some had noticed this error before:

NOTE:
* Both fix configure and configure.in since we can't run the
"autoreconf" for nsrp, please see more explanation in
trickly-fix-build-on-x86_64.patch.
* Also fixed powerpc64, this is just fixed by conclusion since we don't
suport ppc64.
