MIPS: Makefile: Fix MIPS ASE detection code
Commit 32098ec7bcba ("MIPS: Makefile: Move the ASEs checks after setting the core's CFLAGS") re-arranged the MIPS ASE detection code and also added the current cflags to the detection logic. However, this introduced a few bugs. First of all, the mips-cflags should not be quoted since that ends up being passed as a string to subsequent commands leading to broken detection from the cc-option-* tools. Moreover, in order to avoid duplicating the cflags-y because of how cc-option works, we rework the logic so we pass only those cflags which are needed by the selected ASE. Finally, fix some typos resulting in MSA not being detected correctly.
