Reopening and adjusting title to make clear that this is not about using a cross-toolchain, but about multilib support and for this it only needs to fully respect *FLAGS variables.

As an addition, this is a regression against perl-5.16 as the previous major version had no such build failures.

[Comment 3 Mikle Kolyada (RETIRED) 2014-08-01 19:29:05 UTC]

hmm, try with 5.20 then, not sure if i can check it.

Dont expect it to be magically fixed if upstream does not claim so, if the build system partly ignores needed variables, this needs investigation and a patch/fix, otherwise new versions wont change in this regard, so with this in mind:

test with perl-5.20 gives the same result

I am not expected that it is will fixed magically. But if you say, the bug does not affect to perl-5.16 it is probably due to our local gentoo patchset. Since civil always add/remove some patches per version i thought he fix it. But i still not sure if it upstream, but not local regression.

Do not set custom CFLAGS in cpan/Digest-SHA/Makefile.PL

The issue is a very minor one cpan/Digest-SHA/Makefile.PL tries to be smart by overrinding optimization flags as was pointed out by Melker Narikka (meklu).

A straightforward fix is to just remove this optimization nonsene. Patch attached. Tested with perl-5.20

patch worked for me on 5.18.2-r2

[Comment 8 Konstantin M 2014-11-24 13:45:33 UTC]

Patch also worked for me on multilib-portage when adding it to src_prepare() in the ebuild for version 5.20.1-r2. Thanks, Matthias !

[Comment 9 Andreas K. Hüttel 2014-11-29 00:03:27 UTC]

Fixed in 

dev-lang/perl-5.20.1-r3
perl-core/Digest-SHA-5.880.0
