Maybe you need to add a new CT_CC_CORE_EXTRA_SPECS which uses
quoting, e.g.

in scripts/build/cc/gcc.sh

         --disable-nls                               \
         --enable-symvers=gnu                        \
         --enable-languages="${lang_opt}"            \
         ${CT_CC_CORE_EXTRA_CONFIG}
+        "${CT_CC_CORE_EXTRA_SPECS}"
 
Apparently it does not work to type the quotes into
CT_CC_CORE_EXTRA_CONFIG in menuconfig.
