Revert commit 531b3d1195d0 ("MIPS: Loongson: Fix build error when make modules_install"), which made `-march=loongson2e', `-march=loongson2f', and `-march=loongson3a' compilation options probed for even though GCC has supported them since 4.4.0, 4.4.0, and 4.6.0 respectively, which is below our current minimum requirement of 5.1, in an attempt to work around for the `cc-option' `make' function being undefined with `make' targets that do not use the compiler. The workaround has now been made obsolete, by querying the `need-compiler' variable instead so as to make sure the compiler isn't called for non-build targets. Verified with `fuloong2e_defconfig' and the `modules_install' target. Signed-off-by: Maciej W.
