Upsteram Status: Backport
When building on x32 systems where the default type is 32bit, make sure
we can transparently represent 64bit integers. Otherwise we end up with
build errors like:
/usr/bin/perl asm/ghash-x86_64.pl elf > ghash-x86_64.s
Integer overflow in hexadecimal number at asm/../../perlasm/x86_64-xlate.pl line 201, <> line 890.
...
ghash-x86_64.s: Assembler messages:
ghash-x86_64.s:890: Error: junk '.15473355479995e+19' after expression
We don't enable this globally as there are some cases where we'd get
32bit values interpreted as unsigned when we need them as signed.
