Hi,

ippl fails to build from source on loong64 and sparc64 when built with
many parallel jobs:

bison -y -d ippl.y

This is reproducible on stadler.debian.net when building with parallel=16 or more while it works with parallel=8.

Works:

$ export DEB_BUILD_OPTIONS="check bench parallel=8" ; dpkg-buildpackage -B

Doesn't work:

$ export DEB_BUILD_OPTIONS="check bench parallel=16" ; dpkg-buildpackage -B

The problems reminds me of a bug that was fixed in the samba package in 2:4.17.2+dfsg-9 [1].

I had hoped to be able to reproduce it with the new "--shuffle" option of make [2][3] but
that's not the case, unfortunately.

Thanks,
Adrian
