enable cross-compilation of glibc on Darwin (build=Darwin, host=Linux)
|
|
* increase ulimit for open files: macOS default of 256 is too low for glibc build system
|
|
* use host version of ar, which is given by environment variable
|
|
* build system uses stamp.os and stamp.oS files, which only differ in case;
|
|
this fails on macOS, so replace .oS with .o_S
