Subject: cc/gcc: remove --enable-symver option

That option is coming from the original crosstool, and is not entirely
understand here.

Moreover, it breaks with newer gcc-s: 4.6.1 now breaks while configuring
libjava (and probably some other libs as well, untested).

There is an related bug report to the gcc BZ:
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49555

If need be, the old behavior can be restored with:
  CC_CORE_EXTRA_CONFIG_ARRAY="--enable-symver=gnu"
  CC_EXTRA_CONFIG_ARRAY="--enable-symver=gnu"
