Rafael Ávila de Espíndola a8c970acc2 Bug 680277 - Debug builds should always be compiled with frame pointers. r=khuey.
This patch creates a new MOZ_FRAMEPTR_FLAGS variable that is used only to
control the frame pointer flags passed to the compiler. It also computes this
flag in a macro so that the toplevel configure and js/src/configure stay in
sync.
