Hmmm... I neglected to mention that I am using gcc master also. Sorry.

One of the configure conftest.c probes is failing with an object
architecture
variant mismatch.

configure:3595: arm-rtems5-gcc -mthumb -march=armv7-m -mfpu=fpv4-sp-d16
-mfloat-abi=hard -mtune=cortex-m4 -O2 -g -ffunction-sections
-fdata-sections   conftest.c  >&5

With gcc 8.0 trying to head to a freeze, I wonder if you could take a look
at it Sebastian.
