[svn-r3892] Purpose:
    Better Mouse Trap^W^WBug Fix
Description:
    Instead of having the large file support stuff be in the
    config/gnu-flags directory, I added it to the configure.in file so
    that it first checks for the syscall ``getdents64()''. If it finds
    it, then it removes the ``-malign-double'' flag if the GCC compiler
    is 2.95.x since this flag doesn't play well with the LFS stuff.
Solution:
    Added test for getdents64(), if found it removes the -malign-double
    flag if the compiler is 2.95.x. This is done in the configure.in
    file. The gnu-flags file is returned to normal. A new field is added
    to the H5config.h.in file because of the getdents64 check.
Platforms tested:
    Linux
