Tested x86_64-pc-linux-gnu, applying to trunk.
-- 8< --
Recently a mangling test failed on a target with no mangling alias support
because I hadn't updated the expected mangling, but it was still passing on
x86_64-pc-linux-gnu because of the alias for the old mangling. So let's
avoid these aliases in mangling tests.
gcc/testsuite/ChangeLog:
* g++.dg/abi/mangle-arm-crypto.C: Specify -fabi-compat-version.
* g++.dg/abi/mangle-concepts1.C
