Merge branch 'pan/enable_m32_build' into ccase/r13b04_dev
* pan/enable_m32_build:
Teach configure --enable-m32-build for forcing a 32-bit build
OTP-8415 configure learned the option --enable-m32-build to force the
building of a 32-bit run-time on systems where the default C
compiler generates 64-bit executables by default.
