I tried... As soon as the code calls HMAC_Init_ex() it has the linker
issue. But if I test that during configure it just uses libcrypto and
says everything is fine.

This is linker issue
libcrypto.a(rand_win.o):(.text+0xd5b): undefined reference to
`__imp_GetDeviceCaps'
libcrypto.a(rand_win.o):(.text+0xd5b): relocation truncated to fit:
R_X86_64_PC32 against undefined symbol `__imp_GetDeviceCaps'
libcrypto.a(rand_win.o):(.text+0xd88): undefined reference to
`__imp_CreateCompatibleBitmap'
libcrypto.a(rand_win.o):(.text+0xd88): relocation truncated to fit:
R_X86_64_PC32 against undefined symbol `__imp_CreateCompatibleBitmap'

At this point, apart from disabling --without-openssl (it also doesn't
find libcrypto and open-sll on the buildbot) I don't see how to fix
this.
