When loongarch_arch_target is called, la_target has not been
initialized, thus the macro LARCH_ACTUAL_ARCH always equals to zero.
This commit fixes by expanding the macro and reading the latest value.
It permits -march=loongarch64 when the default target is loongarch32 and
vice versa.
gcc/ChangeLog:
* config/loongarch/loongarch-opts.cc (loongarch_config_target):
Fix -march detection.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/arch-1.c: New test.
* gcc.target/loongarch/arch-2.c: New test.
* gcc.target/loongarch/arch-3.c: New test.
