newrepo and toolchains

[kevinresol]

Build toolchains such has hxjava/hxcs does not work with the newrepo command.
Seems that they are still trying to find the toolchain from the global haxelib.

Example:

haxelib run hxcs hxcs_build.txt --haxe-version 3401 --feature-level 1
Error: Library hxcs is not installed
Error: Build failed

This is because the toolchain runs haxelib in the output folder, which does not contain the .haxelib folder. Making a symbolic link to the .haxelib folder works

Setting HAXELIB_PATH=`pwd`/.haxelib explicitly for haxelib run worked for me.

Maybe haxelib run could Sys.putEnv() out of the box to actually allow toolchains with newrepo.

This is fixed since #292.
Now haxelib looks for .haxelib directory recursively up to the root of file system.
