make binary-dist fails for out of tree builds (Cygwin)

[musm]

Cygwin build (test versions of mingw binutils and ld)

1. Make.user contains

XC_HOST = x86_64-w64-mingw32
MARCH=native
OPENBLAS_DYNAMIC_ARCH=0

2. then build
   make -C builddir

3. then change OPENBLAS_DYNAMIC_ARCH=1 in Maker.user in order to build binary-dist, then run

make -C builddir win-extras
make -C builddir binary-dist

output

Build finished. The HTML pages are in _build/html.
