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"

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
     4 MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,
     5 for e500v2 DPFP support) and will generate appropriate dual-precision
     6 floating point instructions by default.

     8 Note: If building a Linux kernel with this toolchain, you will want to make
     9 sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
    10 from getting into the kernel (which is currently unsupported). At this time,
    11 the kernel build system properly passes those two options, but older kernels
    12 were only passing -mno-spe by default."
