[Nim] Can't compile programs with SSL support

[ritcher]

Problem description

It is not possible to compile Nim programs with SSL support.

Steps to reproduce

Write a simple Nim program that requires SSL support.

The program bellow uses Nim's built-in http client to connect to a website via https:

import httpClient
let client = newHttpClient()
echo client.getContent("https://example.com")

Now save the code in a text file and try to compile it with the -d:ssl flag:

$ echo -e 'import httpClient\nlet client = newHttpClient()\necho client.getContent("https://example.com")' > ssl_test.nim
$ nim compile --verbosity:1 -d:ssl ssl_test

Needs -landroid-glob in clang's command line while linking binary.

Added fix in 8acc287.

Alternate way is passing flag -d:termux.
