[Darwin] Suppress emitting empty ctor/dtor sections.
Older versions of GCC emit empty .constructor/.destructor sections
whenever building for C++. In fact, these sections are only used for
kernel mode code - so don't emit them unless that's what we're
building.
gcc/ChangeLog:
2019-10-12 Iain Sandoe <iain@sandoe.co.uk>
* config/darwin.c (darwin_file_end): Only emit empty CTOR/DTOR
sections when building kernel extension code.
