[PATCH][testsuite] Require shared effective target for some lto.exp tests

[PATCH][testsuite] Require shared effective target for some lto.exp tests

Hi all,

The tests in this patch fail for me on aarch64-none-elf with:
relocation R_AARCH64_ADR_PREL_PG_HI21 against external symbol `_impure_ptr' can not be used when making a shared object; recompile with -fPIC

I believe since the tests pass -shared to the linker they should be gated on the 'shared' effective target?
With this patch these tests appear as UNSUPPORTED on aarch64-none-elf rather than FAILing.

Ok for trunk?

Thanks,
Kyrill
