(commit 22905a24306c8c312c2d66da9f90d09af0414f81 upstream)
According to GCC documentation -m(no-)thumb-interwork is meaningless in AAPCS configurations. Also clang does not support the flag: clang-5.0: error: unknown argument: '-mno-thumb-interwork'
Just drop -mno-thumb-interwork in AEABI configuration.
