Makefiles: Simplify auto-derivation of compiler flags
This commit simplifies the logic around automatically setting architecture-specific compiler flags from ``` if (arch == A) { if (!cross) ... if (cross == X) ... elif (cross == Y) ... } elif (arch == B) { if (!cross) ... if (cross == X) ... elif (cross == Y) ... } ``` to ``` if !cross { if (arch == A) ... elif (arch == B) ... ... } else { if (cross == X) ... elif (cross == Y) ... } ``` It also adds further architecture flags for RV64 and PPC64LE.
