Testing gcc-4.4.6 upgrade

Looking in the test suite result, the difference was one test
- busybox-1.17.4 FAIL 'date-R-works'
That fail on gcc-4.4.6 the first time but work the second time I tried.
This test should be racy, it mostly work but sometime fail, so that should
be only noise.

- gdb-7.2 there is less failures, the diff show

   === gdb Summary ===

-# of expected passes  5178
-# of unexpected failures 20
+# of expected passes  5191
+# of unexpected failures 7

So that's not bad.
The full gdb test had some other FAIL, the total FAIL number is reduced from
38 to 25.

Looking at the log diff, using some sed -i -e 's|4\.4\.5|4.4.6|g' to reduce
the noise, I find nothing alarming, just the usual noise log.

So gcc-4.4.6 should just be something good.
The drawback is that there is 497 files that are different and not yet
include in update.
I haven't checked which include gcc version and which are differently
compiled.

Is it the time to update gcc?
