PATCH: Add x32 support to _LT_ENABLE_LOCK

2011-12-12 Thread H.J. Lu 
Hi,

Here is a patch to update _LT_ENABLE_LOCK to support x32:

https://sites.google.com/site/x32abi/home

which is the 32bit ABI for x86-64.  Binutils 2.22 supports -m elf32_x86_64
for x32.

It's not the same.

That section of code is a mess, for all the other systems checking $host 
is correct, for the linux - linux cross compile case, its logic looks 
wrong.
