this breaks feature detection for me on x86_64,
I've got following errors misdetection with this patch:

...                       libperl: [ OFF ]
...                       on-exit: [ OFF ]

and the build fails as well:

  CC       builtin-stat.o
builtin-record.c:42:12: error: static declaration of ‘on_exit’ follows non-static declaration
In file included from util/util.h:51:0,
                 from builtin.h:4,
                 from builtin-record.c:8:
