[libgo] Silence compiler error message

[Eric Botcazou]

Hi,

on Solaris the configuration of the library yields an ugly:

checking whether linker supports split/non-split linked together... cc1: 
error: '-fsplit-stack' is not supported by this compiler configuration
xgcc: error: conftest1.o: No such file or directory
no

Tested on x86-64/Linux and SPARC/Solaris, OK for the mainline?

* configure.ac (libgo_cv_c_linker_split_non_split): Redirect compiler
output to /dev/null.
* configure: Regenerate.
