3When building on x32 systems where the default type is 32bit, make sure
4we can transparently represent 64bit integers. Otherwise we end up with
5build errors like:
6/usr/bin/perl asm/ghash-x86_64.pl elf > ghash-x86_64.s
7Integer overflow in hexadecimal number at asm/../../perlasm/x86_64-xlate.pl line 201, <> line 890.
8...
9ghash-x86_64.s: Assembler messages:
10ghash-x86_64.s:890: Error: junk '.15473355479995e+19' after expression
11
12We don't enable this globally as there are some cases where we'd get
1332bit values interpreted as unsigned when we need them as signed.
