Same. I managed to get rid of about a fifth to a quarter of the errors
with -no-pie -fno-PIE -DFORTIFY=0, which cancelled all the flags shown
by "gcc -v" on a dummy.c file (although running gcc -v -fno-PIE showed
it was running gcc with -fPIE and -fno-PIE on the same command line).

Not that I would be able to use the system I just built - the kernel
build bales out on fs/namei.o with a gcc segfault every time.
