[Toybox] [PATCH] readelf: fix 32-bit build on Android.

[enh]

ptrdiff_t is int rather than long on 32-bit x86 (which is where i happened
to test first; i didn't get as far as arm32), and the compiler doesn't care
that int==long on ILP32 (presumably to help ILP32-first folks from
introducing bugs that only bite LP64 users?).
