the package will reorder CFLAGS, making build fail with clang flags:"-mllvm -polly" Reproducible: Always Steps to Reproduce: 1.using cflags "-mllvm -polly" and build with clang 2. emerge 3. fail

Created attachment 849696 [details] build log in this log you will see the CFLAGS been reorderd to : -Wall -pipe -polly -polly-vectorizer=stripmine -Wno-unused-command-line-argument -march=native -mavx2 -mllvm -mllvm -O3 -flto=thin -fomit-frame-pointer so that -mllvm is not follow by -polly ,causing build fail
