gcc: fix snapshot compile

Add gcc snapshot versions dependency on host-flex and host-bison
(done as suggested by Thomas Petazzoni [1]).

Fixes gcc snapshot version 4.9-20140309 compile failure [2].

Tested the following buildroot configs

BR2_arm=y
BR2_cortex_a9=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
BR2_BINUTILS_VERSION_2_24=y
BR2_GCC_VERSION_SNAP=y
BR2_GCC_SNAP_DATE="4.9-20140309"

and

BR2_arcle=y

For the ARC case disabled the BINUTILS_FROM_GIT host-flex and host-bison
dependency.
