Do you have a suggestion for > something better that doesn't rely on CC_FOR_BUILD? I really have no other idea that’s in scope. After all, CC_FOR_BUILD is the *only* tool guaranteed to correspond to the target (in FreeWRT speak; --build= in GNU autotools speak) system. Not using CC_FOR_BUILD would also break all sorts of cross-compiling, so IMNSHO, that’s *really* out. For x32 (and other upcoming architectures like arm64ilp32), and with the advent of Multi-Arch, this is really a problem (beyond my initial “/bin/sh on x32 is amd64 because it’s linked against klibc, whose x32 build is really amd64 since it lacks explicit x32 support” problem). bye, //mirabilos -- [16:04:33] bkix: "veni vidi violini" [16:04:45] bkix: "ich kam, sah und vergeigte"...
