There are situations in which you might want to build QEMU without
building the full test suite, which in some configurations can take a
considerable amount of time to build. This is especially true when using
LTO with clang. For example:
$ ../configure --cc=clang '--extra-ldflags=-flto=thin -ffat-lto-objects'
'--extra-cflags=-flto=thin -ffat-lto-objects' --target-list=x86_64-softmmu
[...]
$ time make -j8
[...]

$ ../configure --cc=clang '--extra-ldflags=-flto=thin -ffat-lto-objects'
'--extra-cflags=-flto=thin -ffat-lto-objects' --target-list=x86_64-
softmmu --disable-tests
[...]
$ time make -j8
[...]
[2024/2024] Linking target qemu-system-x86_64

Add a toggle to optionally disable building tests.
