d/rules: exclude build flags to enable frame pointers

With frame pointers enabled, inline asm code cannot use rbp, because it is used for the frame pointer. Ubuntu enables frame pointers by default on some arches, so explicitly exclude them to prevent FTBFS issues (LP: #2114228).

This does not currently affect Debian, but we would appreciate if you are willing to accept the patch so that Ubuntu does not need to carry a delta for trinity. Thanks for considering!
