Try making the MCU name uniformly lowercase (msp430g2553).

Hi, I'm moving from to msp430g2553 from msp430f5438a and after some work
I have a clean compile. However I'm getting this linker error. Linking
and running are still okay with the previous chip.
msp430-gcc -o main.elf main.o uart.o ADC.o Timer.o Xref.o -Os -Wall -g
-mmcu=MSP430g2553
/usr/lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld: cannot open linker
script file memory.x: No such file or directory
collect2: ld returned 1 exit status
Makefile:11: recipe for target 'main' failed
make: *** [main] Error 1
I have memory.x files for both chips in
/usr/msp430/lib/ldscripts/msp430f5438a/memory.x and in
/usr/msp430/lib/ldscripts/msp430g2553/memory.x. I'm using DebianMint
2015 so I'm up to date there. I've added the contents of the memory.x
files below. I hope you can help me. Regards Ian.
