Set TESTSUITEFLAGS=-jN in envars

[xry111]

Recently I found setting TESTSUITEFLAGS=-j4 for Tar can significantly accelerate the testing. To me we should just set it for all packages (in LFS book we can add it and MAKEFLAGS into the env command of "Entering the Chroot Environment" as well), instead of do it for specific packages.

Setting MAKEFLAGS per packages used to allows overriding it in BLACK_LIST in optimize/opt_config. But BLACK_LIST is empty now, so the question is whether we might need to use it again... I'd be inclined to keep a per package setting, but adding TESTSUITEFLAGS to the settings.

Looks like only autoconf, bison, kbd, libtool (see below), and tar reference TESTSUITEFLAGS:

In addition, libtool has also a INNER_TESTSUITEFLAGS variable. The problem is that no example in libtool tells whether to pass -jX into TESTSUITEFLAGS or INNER_TESTSUITEFLAGS.

Maybe it should actually be a LFS change.

Replying to xry111:

Maybe it should actually be a LFS change.

I'm not sure what our policy is, respective to timing: should we count everything at -j4 (in which case I think we should pass TESTSUITEFLAGS when calling make check, or are still official timings done at -j1? In the latter case, it would be ALFS job to set TESTSUITEFLAGS=$MAKEFLAGS.

For the record: HARNESS_JOBS=$(nproc) significantly accelerates OpenSSL test suite. This is suitable for all packages using Perl Test::Harness module for testing.

Fixed on the LFS side for a long time.
