Strip only the leading underscore from Mach-O symbols

LLVM prepends an underscore to all Mach-O (Apple) symbols. Previously
we stripped all leading underscores, including ones part of the
function's actual name.

This change will make it possible to support AddressSanitizer
instrumentation, which calls functions such as __asan_report_load_n
which need to be resolved from the dynamically linked runtime.
