It fixes/improves the following:

1. Some code was duplicated.
2. A "The .MIPS.abiflags section has a wrong size" error was not reported as a warning, but was printed to stdout for the LLVM style. Also, it was reported as an error for the GNU style. This patch changes the behavior to be consistent and to report warnings.
3. `unwrapOrError()` was used before, now a warning is reported instead.
