There is a dependency on buildroot's gcc 3.4.6 that probably should be
added.

As for mapping buildroot's target architectures to uMon ports, that
may be unnecessary.  However, the following ports are available in
uMon:

adse_imx21
as3dev
csb250
csb335
csb360
csb472
csb625
csb655
fads860
ads_imx21
bf537
csb272
csb337
csb431
csb535fs
csb637
csb726
mpc852t
v4
altep2c35
csb226
csb281
csb350
csb437tl
csb536fs
csb650
evalsh2
m68en302
walnut

I'm not the best candidate to limit uMon selection to buildroot
architectures that cover those ports.
