Bug#777909: raising severity for GCC 5 issues, please fix these now (see https://wiki.debian.org/GCC5)

[Mike Hommey]

severity 777909 important

AFAICS, GCC 5 is not the default yet, so bumping the severity seems
premature. Moreover the iceweasel version that is in now both testing
and unstable is likely not affected (and it's not like I didn't ask for
a respin for the version in experimental at the time)
