Re: libgo patch committed: Update to Go 1.5 release

["Lynn A. Boger" <laboger@linux.vnet.ibm.com>]

We are seeing failures on all the libgo tests when gccgo is built with 
the latest trunk
on ppc64 (BE) and when running the testsuite for 64 bit.  The failures
do not occur if run on ppc64 BE with m32 and do not occur on ppc64le.

The messages say this:

make[3]: Entering directory 
`/home/boger/gccgo.work/trunk/bld/powerpc64-linux/libgo'
gotest: warning: no tests matching Test([^a-z].*)? in _gotest_.o _xtest_.o
FAIL: bufio
make[3]: *** [bufio/check] Error 1
gotest: warning: no tests matching Test([^a-z].*)? in _gotest_.o _xtest_.o
FAIL: bytes
make[3]: *** [bytes/check] Error 1
gotest: warning: no tests matching Test([^a-z].*)? in _gotest_.o _xtest_.o
FAIL: errors

......  same message for all
