[Regression/Android] Commit e7fb52b3 causes segfault on 32-bit platforms

[Tom Yan]

Hi all,

http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blobdiff;f=lib/stdio-impl.h;h=393ef0cf58d013ec18cfcbb2ee120c4d1df7e028;hp=7a0ac4d50b70c5ad3d3b63d7f3274ba5d6df43a3;hb=e7fb52b3a5ddffe1bba848e4966159868b6951f0;hpb=be18f9170e1989b601a08aada31438cca87cffdd

The definition of fp_ is causing segfault on arm/i686 and doesn't seem
necessary on aarch64/x86_64 as expected either (as of Android 8.0).

See more discussion here: https://github.com/termux/termux-packages/issues/2603

Tom
