Issue: dev-util/shards-0.15.0 does not respect CFLAGS.
Discovered on: amd64 (internal ref: ci)
This machine uses GCC-11: https://gcc.gnu.org/gcc-11/porting_to.html
To reproduce this issue you may want to add "-frecord-gcc-switches" to CFLAGS/CXXFLAGS/FFLAGS/FCFLAGS. If this is not something about c/c++ context see this bug as an hint to hide the QA warning (with QA_FLAGS_IGNORED) where is not possible to respect CFLAGS.
