glog: disable on blackfin external toolchains

With following blackfin toolchains

BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2014R1
BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2013R1
BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R2

when BR2_BINFMT_FDPIC=y

../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)':
../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void'

code snippet at line 95 in elf-fdpic.h
-------------------------------------------------------
unsigned long offset = p - (void*)map->segs[c].p_vaddr;
-------------------------------------------------------

void pointer addition and subtraction is not allowed in C++ as it has undetermined size,
however in C with language extension it is possible because sizeof void is treated
as one byte.

This is toolchain-specific issue. So disable package on these external toolchains.
