Move debug into separate options.
Requested by Matthew Mondor.
readline support require GNU readline.
No sqlite support in PHP-5.4 (only sqlite3).
Set default ABI on Solaris for SPARC too.
Ensure LC_ALL=C is set when determining the gcc version.  Add a comment
explaining why we currently have to hardcode 'env' rather than use SETENV
or PKGSRC_SETENV.
Make curl a tool.  Add support for /usr/bin/curl, if available, on Solaris.

SmartOS and OmniOS users can now set FETCH_USING=curl and no longer require
pkgsrc dependencies for downloading distfiles.
Remove makeinfo requirement, it was added back in 2003 but doesn't appear
to be necessary any more.  Ordinarily it wouldn't hurt to leave it, but it
can cause cyclic dependencies if binutils is required by gcc, and this will
suffice in lieu of a proper fix for that problem.

Update www/moodle to 2.1.7
Use /usr/bin/true instead of : for true. The latter is incompatible with
the use of a colon as a separator, such as in
sed "s:@FOO@:${FOO}"

This unbreaks a variety of packages in MirBSD.
Update to version 20120726.

Major changes:
- Introduce SIGHUP reloading.
- The symlink device can be enabled by '--enable-symlink-device' configure
  option.
- Fix the unknown error under some mutex condition.
- Fix the wrong reservation key handling.
- Use Clang as first choice compiler.
- Use _GNU_SOURCE on linux platform.

Current Limitations of SIGHUP support:
- The parameters other than PG, IG, and LU are not reloaded by SIGHUP.
- PG and IG mapped to LU can't be deleted by SIGHUP.
- If you delete an active LU, all connections of the LU are closed by
  SIGHUP.
- Can't modify LU by SIGHUP.
- Updating IG is not affected until the next login.
Updated net/istgt to 20120726
Sync with net/libfetch/options.mk so that the bundled libfetch can be
correctly built without SSL support.
Pull in the correct libraries when enabling SSL support in libfetch.
Ensure that SSL support is completely disabled if the user has requested
that we prefer pkgsrc for OpenSSL.  While the latter doesn't actually work
yet, it's better that we are deterministic about this and do not pick up
the system OpenSSL regardless.
Add curl tool on Darwin and Linux if it exists, as it is very common.
Convert to modular xorg (by adding/changing dependencies).
Bump PKGREVISION.
NO pkglint cleanup, so if someone ...
Updated emulators/b-em to 2.1anb1
enable reload in rc.d scripts
add patch from upstream to fix bug in MMIO emulation which can cause
guest crashes by unprivileged users, only for HVM guests, and if
MMIO is granted to the user process (CVE-2012-3432)
