I tried building GCC for Android 5 on device and ran into a bunch of errors like 'undefined symbol __swbuf.'  Googling the errors led to this page: https://developer.android.com/ndk/downloads/revision_history.html.

Relevant Part here:

" Removed the following symbols from all architectures: get_malloc_leak_info,free_malloc_leak_info, __srget, __swbuf, __srefill,__swsetup, __sdidinit, __sflags, __sfp, __sinit, __smakebuf,__sflush, __sread, __swrite, __sseek, __sclose, _fwalk,__sglue, __get_thread, __wait4, __futex_wake, __open,__get_tls, __getdents64, and dlmalloc."

Would setting up two repos be advisable...one for 5 and one for 4.x and earlier?
