This approach is simpler than the previous approach which tries to
emulate realpath(3). It also performs much better on both Linux and
OpenBSD on the included benchmarks.
By using realpath(3), we can better integrate with system security
features such as OpenBSD's unveil(2) system call.
This does not use realpath(3) on Windows even if it exists, as the
approach for checking for absolute paths does not work for drive
letters. This can be fixed without too much difficultly, though until
Windows defines realpath(3), there is no need to do so.
For File.realdirpath, where the last element of the path is not
required to exist, fallback to the previous approach, as realpath(3)
on most operating systems requires the whole path be valid (per POSIX),
and the operating systems where this isn't true either plan to conform
to POSIX or may change to conform to POSIX in the future.
glibc realpath(3) does not handle /path/to/file.rb/../other_file.rb
paths, returning ENOTDIR in that case. Fallback to the previous code
if realpath(3) returns ENOTDIR.
glibc doesn't like realpath(3) usage for paths like /dev/fd/5,
returning ENOENT even though the path may appear to exist in the
filesystem. If ENOENT is returned and the path exists, then fall
back to the default approach.
the bug of memmem(3) was fixed in glibc 2.1 released in 1999.

* configure.ac: disable using __builtin_setjmp to avoid errors when execution
globally jumps out of JITted code. Specify -std=gnu99 to JIT compilation
to avoid errors regarding the "restrict" keyword in the precompiled header.
Specify -shared in addition to -Wl,-G when building shared libraries
to make mjit_build_dir.so expose the MJIT_BUILD_DIR symbol. Use LDR_PRELOAD
to load mjit_build_dir.so.
* mjit_worker.c: do not specify -nodefaultlibs or -nostdlibs because on AIX
JITted code internally refers to the memcpy function.

The ruby setting was renamed to HEAP_PAGE_ALIGN_LOG, but the
configure.in (now configure.ac) file was not updated, so the
setting had no effect. The configure setting is unnecessary
after OpenBSD 5.2 and MirOS has been discontinued (with the last
release being over 10 years ago), so it is better to just remove
the related configure setting.

In some places, both JIT and MJIT are being used, but it could be
confusing for new comers. We're not explaining MJIT on NEWS file or release
notes as well. So we consider MJIT as an internal term of implementation
like YARV.

`--disable-mjit`. Default is "enable".
`--disable-mjit` disables all of MJIT features so that `ruby --jit`

This option affect a macro `USE_MJIT`.
This change remove `--enable/disable-install-mjit-header` option.
* Makefile.in: introduce the `ENABLE_MJIT` variable.
* common.mk: use `ENABLE_MJIT` option.
