I think it is just an argument parsing issue.  Turn -v on
and try the command line by hand.  I see a few BSPs doing
similar command lines but without the external file.  We
use that on ar though in the RTEMS Makefiles. 

A couple of examples from the custom files:

gba.cfg:            -Wl,-Map,$(basename $@).map -o $(basename $@).nxe \
pc386.cfg:      $(LINK.c) $(AM_CFLAGS) $(AM_LDFLAGS) 
-Wl,-Ttext,$(RELOCADDR) \
mbx860_005b.cfg:MBX8xx_LDFLAGS=-Wl,--defsym -Wl,HeapSize=0x100000

I think it just isn't getting parsed the same way but the above
work on all the tool versions without change AFAIK.
