[cmake-developers] [PATCH] Fix broken PGI builds for liblzma.

[Chuck Atkins]

I noticed the recent merge of liblzma broke the PGI compiler.  The attached
patch should address the issues:

PGC-S-0037-Syntax error: Recovery attempted by deleting keyword static
(/home/chuck/Code/cmake/source/Utilities/cmliblzma/liblzma/check/sha256.c:
84)

Once that's fixed, then the 32-bit build works but the 64-bit build is
still broken with:

../Utilities/cmliblzma/libcmliblzma.a(sha256.c.o): In function
`lzma_sha256_finish':
/home/chuck/Code/cmake/source/Utilities/cmliblzma/liblzma/check/sha256.c:196:
undefined reference to `__bswap_64'

The patch should address both issues with explanations as to why.
