tools: Fix compilation on x32 host

Compiling the host tools on the new x32 architecture (which is
an ILP32 ELF32 system on an amd64 CPU) fails for various reasons.

 gmp: pull same fix I applied to OpenADK, which was inspired
  by the fix in the Debian source package

 mtd-utils: write a workaround myself; only affects x32, but
  the use of llseek is dangerous according to the manpage, so
  the guard ifdef should probably go away

 findutils: pull fix straight from the Debian source packae

+Subject: [PATCH] Fix time_t vs long int mismatches.
+
+Old gnulibs used randomly either time_t or long int, with a compile-time
+assert to ensure sizeof(time_t) <= sizeof(long int).  This is not the
+case on x32 where the machine word is 32 bit, yet time_t is 64 bit to
+be able to handle dates after 2038.
+
+This is not relevant for modern versions of gnulib which has rewritten
+this code, but, sadly, findutils 4.4.* uses an embedded copy of ancient
+gnulib.
