Build libcurl using mingw32 with static openssl

I try to compile libcurl using mingw32 and a static linked openssl. It
worked in the past, however at the moment I'm unable to do so. The
reason seems to be:

configure:21627: result: no
configure:21655: PKG_CONFIG_LIBDIR will be set to "/home/sithglan/work/vlconnect/curl/../local/win32/openssl/lib/pkgconfig"

Has someone a workaround for this?

I'm building on a 64 bit debian stable from git HEAD of openssl and curl
