Description Agostino Sarubbo gentoo-dev 2020-05-04 06:26:39 UTC
This is an auto-filled bug because media-libs/libmng calls cc directly.
The issue was originally discovered on arm64, but it may be reproducible on other arches as well.
If you think that a different summary clarifies the issue better, feel free to change it.
Attached build log and emerge --info.

If you think it doesn't make sense fix these type of issues, I'd like to point out that won't be possible use a different CC implementation (like clang) by setting the CC variable. So this issue has been reproduced by setting the CC variable to aarch64-unknown-linux-gnu-gcc and by removing the /usr/bin/cc - /usr/bin/gcc binaries.

    media-libs/libmng: don't call 'gcc' in src_prepare(), bug #720884
    Before the change src_prepare() was calling 'emake distclean'.
    That forced reconfiguration with default CC=gcc.
    The change just deletes files which 'make distclean' would delete.
