PKGSRC_USE_MKTOOLS support added



Hey all,

As proposed a few weeks ago, I've now added the support for C-based tools to speed up various parts of the mk infrastructure. You can opt in to the support (it currently defaults to off) with:

  PKGSRC_USE_MKTOOLS=yes

in your mk.conf.

For packages with large numbers of dependencies, you should see anywhere up to around 10x speed-up for the 'wrapper' phase, and perhaps more importantly a huge reduction in system time usage.

I'd love to get feedback on whether this works for you on exotic platforms. I'm using it without issues on macOS and illumos, and have had positive reports from NetBSD users. I'll also be turning it on for all my daily bulk builds. Hopefully we can switch the default to yes in the future.

Cheers,

Log Message:
mk: Add PKGSRC_USE_MKTOOLS support.

When enabled, pull in the pkgtools/mktools package to use C-based tools for
certain parts of the pkgsrc mk infrastructure.  Default is off for now while
any portability issues are shaken out, but it has been tested successfully on
at least illumos, macOS, and NetBSD.

The first tool is mk-buildlink-symlinks which creates the buildlink3 symlinks
as part of the "wrapper" phase.  This significantly improves performance,
especially with packages that have a lot of buildlink3 dependencies.  For
example, the time for "bmake wrapper" in x11/kde-workspace4 goes from:

  real     3:20.696394375
  user       50.553556463
  sys      2:23.883823896

to:

  real       19.873100598
  user        8.141441461
  sys        11.740602820

It's expected that other tools will be added over time to speed up other parts
of the infrastructure.
