With Cygwin, AC_PATH_PROG needs Cygwin-style paths

(And instead directly specifying CLANGDIR as a Cygwin-style path in my clang-cl
build's autogen.input doesn't work, as compilerplugins/Makefile-clang.mk spells
a dependency on

  $(CLANGDIR)/bin/clang$(CLANG_EXE_EXT)

which Make on Windows requires to be a Windows-style path.)
