The D programming language needs a runtime, named libgphobos. When
building a toolchain with uclibc-ng as libc, for qemu_aarch64_virt, the
following error occurs:

```
libtool: compile:  /home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/build/host-gcc-final-9.2.0/build/./gcc/gdc -B/home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/build/host-gcc-final-9.2.0/build/./gcc/ -B/home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/host/aarch64-buildroot-linux-uclibc/bin/ -B/home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/host/aarch64-buildroot-linux-uclibc/lib/ -isystem /home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/host/aarch64-buildroot-linux-uclibc/include -isystem /home/eric/build/demo-dlang/qemu/aarch64/virt/uclibc/host/aarch64-buildroot-linux-uclibc/sys-include -fPIC -O2 -g -nostdinc -I ../../../../libphobos/libdruntime -I . -c ../../../../libphobos/libdruntime/core/internal/abort.d -fversion=Shared -o core/internal/.libs/abort.o

 1134 |         byte[__SIZEOF_PTHREAD_ATTR_T] __size;
      |                                       ^
```

I haven't dug into uclibc-ng code to find out the cause of the error.
Hence the restriction to a glibc-based toolchain.
