Description Alexey 2017-01-15 01:01:44 UTC
I have CC="clang" CXX="clang++" in /etc/portage/make.conf
When trying to compile cross-armv7a-hardfloat-linux-gnueabi/glibc-2.23-r3:2.2, it tries to use clang instead of armv7a-hardfloat-linux-gnueabi-gcc, and fails with error "too old compiler".

Reproducible: Always

Steps to Reproduce:
1. Set clang as default compiler in make.conf
2. emerge cross-armv7a-hardfloat-linux-gnueabi/glibc
Actual Results:  
clang is used, and ./configure fails

Expected Results:  
armv7a-hardfloat-linux-gnueabi-gcc should be used, because crossdev was initialialized with gcc, not with clang

Attaching the patch which I think should fix this. I managed to compile glibc only when I added this to /etc/portage/env/cross-armv7a-hardfloat-linux-gnueabi/glibc.conf
