Using custom linker scripts with mspgcc

I'm trying to integrate some custom linker sections using mspgcc using
the following faq:
http://mspgcc.sourceforge.net/faq/x71.html

Which tells me to do this:
msp430-gcc -Wl,--section-start -Wl,-T linker_script.x [other options and files]

However, when I do that, I get the following error:
/usr/local/msp430/bin/../lib/gcc/msp430/4.7.0/../../../../msp430/bin/ld:
invalid argument to option "--section-start"

if I leave that off, I get:
/usr/local/msp430/bin/../lib/gcc/msp430/4.7.0/../../../../msp430/bin/ld:
internal error emsp430.c 123

Which leads me to believe that either the --section-start is special
for the msp430-gcc, or the linker isn't accepting the multiple -T
options, and accumulating as expected.

Any ideas on what I could be doing wrong?  Examples of what other
folks are doing might be helpful.

mspgcc version:
msp430-gcc (GCC) 4.7.0 20120322 (mspgcc dev 20120911)


The linker command line I'm using:
/usr/local/msp430/bin/msp430-gcc   -mmcu=msp430fr5969
-ffunction-sections -fdata-sections -DGCC_MSP430 -Wextra
-fno-exceptions -fno-rtti -fno-enforce-eh-specs -lfp -lm -g
