This is wrong. Passing the flags to configure using environment variable is
deprecated since even before the birth of the Xenomai project.
TARGET_CFLAGS and TARGET_CXXFLAGS are not used anywhere by Xenomai build system.

How does the xenomai configure script get the correct cross compiler settings?
Is it just a matter of using --host to specify the target cross compiler?
./configure --host=i686-angstrom-linux
I had some problems early on when the xenomai configure script would use the
build system compiler rather than the cross compiler. Obviously the cross
compiler has to be in the build environment path environment. Is it best to
leave all other compiler flags unset when running configure?
