Currently, build.sh would reject that as invalid.  It knows the
following MACHINE/MACHINE_ARCH settings for hpcarm:

MACHINE=hpcarm          MACHINE_ARCH=arm        DEFAULT
MACHINE=hpcarm          MACHINE_ARCH=earm       ALIAS=hpcearm

If you want earmv4 to be the default, you could change those lines,
perhaps to something like:

MACHINE=hpcarm          MACHINE_ARCH=arm        ALIAS=hpcarm-old
MACHINE=hpcarm          MACHINE_ARCH=earm       ALIAS=hpcearm
MACHINE=hpcarm          MACHINE_ARCH=earmv4     ALIAS=hpcearmv4 DEFAULT

The MACHINE_ARCH tagged "DEFAULT" is used if you run build.sh with 
"-m MACHINE" and without "-a MACHINE_ARCH".  The "ALIAS" is usable 
as a shorthand, where running build.sh with "-m ALIAS" implies "-m 
MACHINE -a MACHINE_ARCH".
