[Pkg-cmake-team] Bug#916487: cmake: Please add small workaround for m68k

[John Paul Adrian Glaubitz]

Source: cmake
Version: 3.13.2-1
Severity: normal
User: debian-68k at lists.debian.org
Usertags: m68k

Hello!

We are currently having issues with cmake on m68k locking up, most
likely related to a bug in libuv as the problem first showed up
with cmake 3.11.0 which integrated more libuv code in cmake.

After long debug sessions, I have come up with a temporary workaround
which addresses the issue by using the embedded copy of libuv and
dropping the Debian-specific build flags.

This is considered a workaround and therefor esupposed to be used
temporarily once we have hunted down the actual bug, most likely
in libuv.

Could you apply the attached patch for the next cmake upload so we
can remove the "Not-for-us" flag for cmake on m68k?

Thanks,
Adrian
