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

[Vladimir Kozlov]

On MacOS we also have problem when 'ld' is present on path but Xcode is missing:

% /usr/bin/ld -v
xcode-select: error: no developer tools were found at '/Applications/Xcode.app', and no install could be requested (perhaps no UI is present), please install manually from 'developer.apple.com'.

AOT tests will fail in such case too. May be AotCompiler test code also have to execute ld -v (or ld -V on Solaris) to check that we can use linker similar to JAOTC tool:

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.
