Details

xz has the tendency to murder _low end boxes_ with little RAM with the compression level (-6) it default's to. Make this adjustable in /etc/makepkg.conf for people who do not want to distribute packages and instead want faster compression.
This task depends upon

You don't have to compress at all, pkg.tar is fine. Or use gz.

A similar issue https://bugs.archlinux.org/task/20954 but for mkinitcpio (and it was about lowering it *to* -6) - maybe we can reuse the ${COMPRESSION_OPTIONS} code?

It does seem just as easy to disable compression altogether or switch to the more friendly gzip, not that I see no benefits in allowing the compression options to be tweaked.

You can just set the XZ_OPT environment variable to '-1' (see the xz man page).

with export XZ_OPT=-9:
-rw-r--r-- 1 strcat users 22M Sep 12 21:56 android-ndk-r6b-1-x86_64.pkg.tar.xz

and export XZ_OPT=-1:
-rw-r--r-- 1 strcat users 37M Sep 12 21:56 android-ndk-r6b-1-x86_64.pkg.tar.xz
