OABI_COMPAT option in kernel missing for arm

Hi,

I am compiling a buildroot on an arm em-x270 board.
The kernel compiled from the buildroot hangs on init because the Makefile.in.advanced removes the OABI_COMPAT option.
Infact, when compiled with EABI, the buildroot script target/linux/Makefile.in.advanced removes any OABI_COMPAT options but my arm target requires that option to work.
I have solved my problem with a simple "#" in the Makefile.in.advanced, but maybe that should be fixed .
Should I open a bug report?
regards,
