# Exclude punybench from clang build.  It uses the -pg flag
# which causes clang, by default, to generate the symbol
# "mcount", which the linker cannot resolve.  Passing
# "-meabi gnu" fixes that issue by causing clang to generate
# "__gnu_mcount_nc" instead, but LLVM's current implementation
# of that is incorrect and can corrupt the stack pointer.
