Public bug reported:
While this might be a kernel build problem (see LP: #1939308) I wanted
to raise the issue against the toolchain just so we can make sure it's
*not* a toolchain bug. Basically the following behavior changed from gcc
10:
$ arm-linux-gnueabihf-gcc-10 -march=armv7-a -c -x c /dev/null ; echo $?
0
$ arm-linux-gnueabihf-gcc-11 -march=armv7-a -c -x c /dev/null ; echo $?
cc1: error: ‘-mfloat-abi=hard’: selected architecture lacks an FPU
1
Presumably the GCC 11 hard-float compiler now enforces the default
config --with-float=hard?
