[Buildroot] [PATCH 27/29 v2] package/sdcc: add option for the device lib

[Yann E. MORIN]

This enables the "stdlib"-like set of libraries for the enabled ports
and for the various memory models supported by each port.

For some ports, there are non-fee libraries (and includes) available.
However, their licensing terms are dubious, and they are only available
for the PIC ports which we currently do not enable in Buildroot. So we
do not enable those non-free stuff.
