* configure.ac: Check for sys/mman.h and mmap. Check for mremap
with MREMAP_MAYMOVE.
* output.h (class Output_file): Add map_is_allocated_ field.
* output.cc: Only #include <sys/mman.h> if it exists. If mmap is
not available, provide stubs. If mremap is not available, #define
it to gold_mremap.
(MREMAP_MAYMOVE): Define if not defined.
(Output_file::Output_file): Initialize map_is_allocated_.
(Output_file::resize): Check map_is_allocated_.
(Output_file::map_anonymous): If mmap fails, use malloc.
(Output_file::unmap): Don't do anything for an anonymous map.
* fileread.cc: Only #include <sys/mman.h> if it exists. If mmap
is not available, provide stubs.
(File_read::View::~View): Use free rather than delete[].
(File_read::make_view): Use malloc rather than new[]. If mmap
fails, use malloc.
(File_read::find_or_make_view): Use malloc rather than new[].
* gold.h: Remove HAVE_REMAP code.
* mremap.c: #include <errno.h>. Only #include <sys/mman.h> if it
exists. Rename mremap to gold_mremap. If mmap is not available
don't do anything.
* configure, config.in: Rebuild.
