I was wondering if the fact of 
adding a full path could have an influence.
So I tested 4 variants (on GDB-7.4 sources)
Variant 1) Using just 'gmake'
Variant 2) Using '/usr/local/bin/gmake'
Variant 3) Using 'gmake all-gdb'
Variant 4) Using '/usr/local/bin/gmake all-gdb'

Clearly, only variants 1 and 2 complete successfully,
while variants using all-gdb
do have
MAKE = make
instead of
MAKE = 'gmake as called, i.e. with or without path'


There are differences in the gdb/Makefile's (see below)
but I have no idea if this explains the
failure with all-gdb target.
