Both MinGW and cygwin (i686) construct export directives without the global leader prefix. This is mostly due to the fact that they use GNU ld which does not correctly handle the export directive. This apparently has been been broken for a while. However, this was recently reported as being broken by mingwandroid and diorcety of the msys2 project. Remove the global leader prefix if targeting MinGW or cygwin, otherwise, retain the global leader prefix. Add an explicit test for cygwin's behaviour of export directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207926 91177308-0d34-0410-b5e6-96231b3b80d8
