the correct circumstances of DMA buffer size, serial
line interrupts, and ethernet interrupts the termios osend routine would
lock up waiting for the raw output buffer semaphore.
that does the following:
Changes:
Remove $(SED) and $(CP) from make/custom/*.cfg
Motivation:
* autoconf and automake presuppose sed and cp to be present.
* make/host.cfg.in already contains SED = sed hard-coded into it for
a long time.
* Elimination of make-variables
* Eliminate make/*.cfg files or at least reduce their complexity :)
That BSP now has a stub clock driver so the tests can link even
if they won't execute. A handful of Makefiles had to be updated
and we had to account for printk.c being a shared file now.

of Canon CRF - Communication Dept. This port includes a
basic BSP that is sufficient to link hello world.
a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.

This update addresses the following:
+ the ISR enable/disable/flash macros now work with old gcc versions.
+ the UI CCR bits are now masked since other example code did so
+ _ISR_Dispatch disables interrupts during call setup
Together these removed the instabilities he was seeing.
