build.sh accepts flags, but then:

|clang++: warning: ignoring '-mlong-calls' option as it is not currently supported with the implicit usage of -mabicalls [-Woption-ignored]

... second attempt, diff below:

|> clang++ -x c++ -std=c++11 -pthread -mlong-calls -mno-abicalls -Wno-deprecated-declarations -DNDEBUG bindjam.cpp [...] -o b2
|fatal error: error in backend: Cannot select: 0x45fc4c9a0: i64 = MipsISD::GPRel TargetGlobalAddress:i64<ptr @.str> 0 [TF=3]
