icecc.bbclass: blacklist libgcc-initial

Building libgcc-initial with IceCC enabled can fail with the CPP sanity
check error in the following case (using ARM for example):
* sysroot contains cross gcc built for another ARM variant
* sysroot contains initial cross gcc built to suit the target machine
* bitbake tries to configure libgcc-initial
* libgcc-initial calls icecc wrapper
* icecc wrapper calls non-initial cross gcc via the full path
* non-initial cross gcc looks for the headers in the wrong place
* BOOM
