perl5.24.0-RC5: broken build

[mojca (Mojca Miklavec)]

Building perl 5.24.0-RC5 in the same way as any other older Perl version breaks for me:

env MACOSX_DEPLOYMENT_TARGET=10.7 /usr/bin/clang -o libperl.dylib \
    -L/opt/local/lib -Wl,-headerpad_max_install_names \
    -arch x86_64 -fstack-protector -dynamiclib \
