I.e., IP27 or IP32 builds (or IP30 out-of-tree) don't emit this error, but building IP28 systems in-tree will cause it to appear quite a bit. The message itself, I believe is complaining that the stated CPU ISA (mips1 ... mips4, mips32r2, r10000, etc) in one of the sections (e.g.,.MIPS.abiflags) doesn't match the equivalent ISA value in the other section (e.g., e_flags). I haven't seen any harmful side effects of it myself. Seems to be more of a warning than anything else, and as long as the ISA matches a supported CPU (e.g., r10000 is compatible with mips4), it can be ignored. It does clutter up the build, though."
