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

base-files: add /etc/shadow to list of essential files to keep in sysupgrade (bug 18206)

Based on bug #18206 sysupgrade can lead to loss of password information in
certain situations. Most likely all users who will upgrade from versions
r43017-43040, will lose their current passwords. :-(
https://dev.openwrt.org/ticket/18206

Currently /etc/shadow is defined as a conffile in base-files:
https://dev.openwrt.org/browser/trunk/package/base-files/Makefile#L37

But it is not defined in the default list of essential files to keep in
sysupgrade:
https://dev.openwrt.org/browser/trunk/package/base-files/files/lib/upgrade/keep.d/base-files-essential

If exporting conffiles info fails, /etc/shadow can get lost.

Shadow passwords are now the default, so saying that preserving /etc/passwd
is essential while /etc/shadow is not, makes no sense.

The attached patch adds /etc/shadow to the list of essential files.
