[PATCH 0/3] minimum.exe Size Reduction Patches

This patch set is the culmination of the recent inquiry into why
some BSPs have a minimum.exe around 32K of text and others are 
twice that. This addresses two unnecessary dependencies that
resulted in ~25K reductions in minimum.exe for the jmr3904
and psim BSPs.

I plan to make a sweep in the near future of all BSPs to see if
there are reasons a specific BSP has a minimum.exe that is
larger than expected. I would eventually like to have a list
of some key symbols that minimum should not have in it. If we
had that for a few of the smaller tests, this would be helpful.

Joel Sherrill (3):
  ppc-irq-legacy.c: Use rtems_malloc() instead of malloc().
  powerpc/.../sbrk.c: Do not reference errno.
  sysinit: Do not open console when just referencing reentrancy
