bug#17971: 24.3.92; Patch to fix el compression on RHEL/CentOS 7

[Stephen Hassard]

For fun I built a copy of findutils-4.5.12 from alpha.gnu.org and found that it's suffering the same regression as CentOS's bundled find.

It's definitely a regression in CentOS7 vs 6.5. I've built a new 6.5 VM and have confirmed that it compresses the .el files without problem.

It seems to be a regression in the bundled findutils. I've pulled in the find binary from CentOS 6.5 onto my CentOS 7 VM and the 'make install' process completed without problems with the old find.

The version are:

CentOS 7:

findutils-4.5.11-3

CentOS 6.5:

findutils-4.4.2-6

Do you know why this happens?
What has changed since RHEL6, where it works fine?

This fails if DESTDIR contains spaces.
