erlang: add option to enable SMP support

Browse Source 
Erlang builds two emulators depending on whether SMP is supported or
not. If it is known that the target does not support SMP, turning off
the SMP emulator saves compile time and reduces the size of the
installation.

help
Erlang provides both a UP and an SMP emulator. The UP emulator
is always built, and this option enables compilation of the SMP
emulator. The choice of which emulator to use is made at runtime.
If you do not need SMP support, turning this option off reduces
compile time and the size of the Erlang installation.

help
The Megaco application is a framework for building applications
on top of the Megaco/H.248 protocol. It is approximately 14MB in
size so if you do not need it then it is recommended not to
enable it.
