Re: [Energia] mspgcc in path with spaces -> linking issue

Generally you should use msp430-gcc as the driver since it will add
necessary additional linker flags.  In this case, the simpler solution
might be to use msp430-ld directly since what it adds doesn't work.

I don't plan to investigate this but if anybody does: the issue is probably
because msp430-gcc needs to extract the MCU from the command line and
generate an additional parameter to the linker to tell it where to find
mcu-specific files.  This is done in file gcc/config/msp430/msp430-gcc.c in
the gcc source, in function msp430_mculdscriptpaths.  The resulting string
is inserted into the GCC specs file and processed by the shared driver
code.  The syntax and processing of the specs file is described at
http://gcc.gnu.org/onlinedocs/gcc-4.7.2/gcc/Spec-Files.html#Spec-Files

It may be as simple as having msp430-mculdscriptpaths add quotes around the
path value, but it may not as I don't recall seeing that specs file
tokenization pays attention to quotes.  If there's a way to represent a
path that includes spaces, the specs file document should explain it.

If a solution is found, please make sure the problem and solution are
reported on the mspgcc project tracker so it can be reviewed for
incorporation into any future releases.
