Of course, MacOSX only has posix_memalign, and only in recent versions.
(Older versions could use valloc instead. That precludes ever changing
the LMDB pagesize to be different from the OS pagesize.) Not all that
crucial since it only affects mdb_env_copyfd1.

1e7eeed28d Fix loose pages in mdb_freelist_save(). 
Leaving them in dirty_list caused breakage.  Instead merge them
into me_pghead at the end, when no more pages will be allocated.

Everything has it. Solaris doesn't have posix_memalign.

3630066843 Fix MIPS cache coherency on Linux 
MIPS chips require manual control of on-chip caches. The cacheflush
syscall being used here only exists on MIPS Linux, other OSs will
require revisiting.
