When running b2 inside a qemu mixed mode environment (32 inside 64) it errors with some system calls not properly translating from 64 to 32. This works around the problem by making the 32 bit b2 build use 64 bit file system calls in libc. Potentially fix for: * https://github.com/bfgroup/b2/issues/49 * https://github.com/conan-io/conan-center-index/issues/6059 * https://github.com/boostorg/build/issues/663
