Moved -qnolinkcmds option so arguments passed on the command line are
interpreted at the right point per Eric Norum's discovery:
The problem with the my previous `fix' for adding linker commands
was with the ordering of the options to the linker.
For example, to make a larger heap size, the application Makefile would
CFLAGS_LD = -Wl,--defsym -Wl,HeapSize=0x40000
The command passed to the linker would be :
m68k-rtems-ld .... -T xxx/linkcmds .... --defsym HeapSize=0x40000 .....
This doesn't work because the script in linkcmds inserts a default
value for HeapSize if HeapSize is not defined by the time the linker
looks at the linkcmds script.
The solution seems to be to move the -T linkcmds%s in the bsp_specs
file out of the link specfication and into the lib specification -- a
little unorthodox, perhaps, but it seems to work!
