[Buildroot] [PATCH 26/29 v2] package/sdcc: add option for the z80 port

[Yann E. MORIN]

The z80 is a common microprocessor familly, and although it is currently
unused in Buildroot, it makes sense to enable to demonstrate how to
enable ports other than the mcs51.

Note that we decided to add a single option that enables all the
variants of z80, rather than one for each variant: this only installs a
single additional program that handles all z80 variants anyway. When the
device libs are enabled, one set of libs is installed for each variant,
though they are small enough that it does not warrant adding an option
for each variant.
