Can't build gcc for msp430. Failing in stage two with the following error message (in the log file): checking for library containing clock_gettime... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

Please note this is a different problem then the one I'm having with 4.9.2 (i.e. I don't believe they're duplicates).

looks like newlib is broken: configure:3949: $? = 1 configure:3965: /var/tmp/portage/cross-msp430-elf/gcc-5.1.0/work/build/./gcc/xgcc -B/var/tmp/portage/cross-msp430-elf/gcc-5.1.0/work/build/./gcc/ -B/usr/msp430-elf/bin/ -B/usr/msp430-elf/lib/ -isystem /usr/msp430-elf/include -isystem /usr/msp430-elf/sys-include -o conftest -g -O2 conftest.c >&5 /usr/msp430-elf/lib/libcrt.a(crt_callexit.o): In function `.Loc.118.1': /var/tmp/portage/cross-msp430-elf/newlib-2.2.0.20150225/work/newlib-2.2.0.20150225/libgloss/msp430/crt0.S:118: undefined reference to `_exit'
What I did to work around this build issue is to add EXTRA_ECONF="--enable-libstdcxx-time=no" to /etc/portage/env/cross-msp430-elf/gcc.conf the same workaround fixes it on cross-arm-none-eabi/gcc as well.
This is now a problem on gcc-4.9.3 as well. Joakim's solution works for me. It seems like perhaps this is something that should be added to the cross-compilation setup.
