Just wire things up to make the project buildable
on LoongArch64.
opensslconf.h is taken form riscv64 folder as is,
and is the same as on some other 64 bit architectures.

Since commit b98c56fd5e ("stop exposing
hidden defines in public opensslconf.h"), only a subset of CPU
architectures is supported by libressl. However, when a build is
attempted for an unsupported architecture, it doesn't fail with a
clear error message at configure time, but it fails with a weird error
at build time:
crypto/../include/openssl/rc4.h:75:9: error: unknown type name 'RC4_INT'
In order to help users, let's bail out nicely at configure time with a
good error message when the CPU architecture is not supported.

Internally LIBRESSL_SKIP_INSTALL, if not set becomes ENABLE_LIBRESSL_INSTALL so this by default is enabled. defining LIBRESSL_SKIP_INSTALL before hand will disable all install() rules.
This is useful if another project includes and links to this statically.
I chose to add a prefix to avoid potential name collision because the options are cached globally.
If the installation is skipped, maybe it should also disable building apps? I didn't do that.
- modify structure of CMakeLists.txt under apps/
* move apps/CMakeLists.txt to apps/openssl/ since this is for openssl build
* create new apps/nc/CMakeLists.txt for nc build
* modify apps/CMakeLists.txt just add_subdirectory()
- add checking and compile of arc4random_uniform()
- add installing man files, openssl.1 and nc.1
