Yes, potentially.
Winpthreads can be built in a number of different scenarios. The regular
one is where it is built like any user library, when you already have a
fully working toolchain. In this case, configure time link tests should
work (but I'm not sure if AC_NO_EXECUTABLES makes them not do that).
But for GCC setups where libgcc/libstdc++ uses winpthreads as threading
backend, winpthreads needs to be built before you have built libgcc, so
any regular linking test will fail, as the toolchain is yet incomplete.
That's why the build of winpthreads tries to supply a small dummy libgcc
which is used during the build instead.
