- Subject: [committed][MSP430] Only add crtn.o to ENDFILE_SPEC if it exists
A recent patch to Newlib (commit 884b05b54) removes crtn.o for msp430.
This patch wraps uses of crtn.o in ENDFILE_SPEC from config/msp430.h in
if-exists, so compatibility with new and old newlib is maintained.
Committed on trunk as obvious.
