[Mono-list] Fwd: [PATCH] mono-4.xx.inc: disable parallel make

[Chris Morgan]

Hello.

I had posted last week about issues during the install phase of a
build due to the same file being installed multiple times.

>From another user with the same issue it looks like the issue may be
related to parallel make.

Is this a known limitation when building mono?

A race was observed during `make install` of mono-native under
PARALLEL_MAKE=-j6:

/usr/bin/install: cannot change permissions of
build/tmp-glibc/work/x86_64-linux/mono-native/4.0.2.4-r0/image/
build/tmp-glibc/sysroots/x86_64-linux/usr/lib/mono/xbuild-frameworks/
.NETFramework/v4.5/RedistList/FrameworkList.xml: No such file or
directory

This is definitely a race, because FrameworkList.xml was present once
the failed build completed.

The present mono build doesn't appear to build much of anything in
parallel in the first place, and I would guess that this issue applies
equally to the mono and mono-native builds. So the correct place for the
workaround ought to be in the shared .inc file.
