Paolo Bonzini 4fd56724ad Use Jenkins hash.
This is about twice as fast as the current hash, and removes the
need for double hashing (improving locality of reference).  The
hash function is based on Bob Jenkins' design, slightly adapted
wherever Make needs to hash NUL-terminated strings.  The old hash
function is kept for case-insensitive hashing.

This saves 8.5% on QEMU's no-op build (from 12.87s to 11.78s).

* configure.ac: Check endianness.
* hash.c (rol32, jhash_mix, jhash_final, JHASH_INITVAL,
sum_get_unaligned_32, jhash): New.
* hash.h (STRING_HASH_1, STRING_N_HASH_1): Use jhash.
(STRING_HASH_2, STRING_N_HASH_2): Return a dummy value.
(STRING_N_COMPARE, return_STRING_N_COMPARE): Prefer memcmp to strncmp.

Test the behavior of the .SECONDARY special target.
Create a makefile where a file would not normally be considered
intermediate, then specify it as .SECONDARY. Build and note that it's
not automatically deleted. Delete the file. Rebuild to ensure that
it's not created if it doesn't exist but doesn't need to be built.
Change the original and ensure that the secondary file and the ultimate
target are both rebuilt, and that the secondary file is not deleted.
Try this with implicit rules and explicit rules: both should work.\n";
