www/node: fix SSL/TLS on i386
The upgrade to v10.0.0 included significant changes to the OpenSSL
dependency in Node.js, in particular how the build was configured.
Upstream does not include a BSD-x86 config anymore, so the www/node port
ended up using the BSD-x86_64 no-asm config for all builds except x86_64
(which used the asm optimized config). This was a mistake, causing all
32-bit archs to build OpenSSL configured for a 64-bit architecture, and
it causes problems with SSL/TLS as described in PR 228135.
Change the build config to not use BSD-x86_64 no-asm for 32-bit i386 and
arm builds, falling back to the generic linux-elf configuration instead.
Patches remove Linux specific libraries (-ldl) and keep the CFLAGS the
same as the BSD config.
