On a tumbleweed system, "install X Y" was showing the error: pseudo: ENOSYS for 'fsetxattr'. which was being caused by dlsym() for that function returning NULL. This appears to be due to it finding an unresolved symbol in libacl for this symbol in libattr. It hasn't been resolved so its NULL. dlerror() returns nothing since this is a valid symbol entry, its just not the one we want. We can add the glibc version string for the symbol we actually want so we get that version rather than the libattr/libacl one. The calls in libattr are just wrappers around the libc version so our attaching to the libc versions should intercept any accesses via these too.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
