Have the linker search /usr/local/lib on Linux

[define-private-public]

This was causing some issues when I was trying to link a .so of raylib and glfw. /usr/local/lib wasn't in the -rpath option at link time on Linux. It is a common location for users to install libraries on Linux and should be part of the link path.

This breaks travis:

/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.o: In function `nimUnloadLibrary':
/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.c:(.text+0x10a91): undefined reference to `dlclose'
/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.o: In function `nimLoadLibrary':
/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.c:(.text+0x10ac5): undefined reference to `dlopen'
/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.o: In function `nimGetProcAddr':
/home/travis/build/nim-lang/Nim/nimcache/stdlib_system.c:(.text+0x10b01): undefined reference to `dlsym'

@Araq this breaks Travis because of compiler bug, for some reason clang compiler was set as default compiler... And we don't using clang as default compiler on Travis.

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is there something I need to change in the travis CI file?

That's really strange. Maybe you could try rebasing?

No feedback, breaks clang, closing.
