Fix HiPE debug lock checking on OS X 64bit

Position-independent code is mandatory on OS X. We use r11 as an intermediate
register to fill BIF_P->hipe.bif_callee. This fixes the following error when
doing `make debug FLAVOR=smp`:

clang -cc1as: fatal error: error in backend: 32-bit absolute addressing is not supported in 64-bit mode
Install internal hrl files when necessary

Sometimes we install *.erl files. Some these files include a private
*.hrl files, so in order to make these *.erl files usable we have to
install these private includes as well.
