- no need to patch and search and replace on packagelist.txt when a
simple patch will do
- fix name of the epm patch
- disable parallel builds. Our user-land pthreads lib converts fd's to be
non-blocking which causes intermittent build failures when a parallel
process can't deal with non-blocking fd's. For example cat and stdout.
parallel builds will need to wait for rthreads.
