Yep, looks good.

Also fine

> compel/Makefile:44: HOSTCFLAGS are -I__BUILD_HOST__/platform-imx6/sysroot-host/lib/pkgconfig/../../include -march=armv7-a -march=armv7-a -O2 -g -Wall -Wformat-security -Werror -DCONFIG_ARMV7 -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE  -iquote include/  -DNO_RELOCS

Here is in the host's CFLAGS "-march=armv7-a" - that looks wrong.
Please, run instead with attached diff - it should fix this problem.

That absolutely ok.
