buildroot: allow enabling MIPS16 user-space build

Browse source 
Enabling MIPS16 is made conditional on advertising the "mips16" feature
for a specific target since it requires support from the CPU
(HAS_MIPS16) and the actual use of MIPS16 for building packages
(USE_MIPS16).

help
If your target CPU does support the MIPS16 instruction set
and you want to use it for packages, enable this option.
MIPS16 produces smaller binaries thus reducing pressure on
caches and TLB.
