RFR(XS) : 8187020 : AOT tests should not fail if devkit dependency isn't resolved

[Igor Ignatyev]

Hi Vladimir,

I've added a check that ld -v/-V exits gracefully, compiler/aot tests have been rerun on major platforms.

Thanks,

Prior this fix, the tests would fail w/ FileNotFoundException when devkit dependency can't be resolved even if jaotc is able to find a linker, e.g. in one of VS*COMNTOOLS. after this fix, if tests aren't able to download devkit, they will allow jaotc to try to find a linker. This patch also remove search for 'ld' in PATH on windows b/c jaotc doesn't use it on windows.
