vapier noted these problems way back with 3.4.6 and there seem to be several bugs related to this.

GCC_NO_EXECUTABLES is a generic error that another problem eventually triggers

you need to post full logs as attachments like crossdev told you to

you'll also need to extract the config.log files from the gcc build directory

I got around this by disabling the 'mudflap' use flag after installing glibc with CROSSCOMPILE_OPTS="headers-only".
