[PATCH] Fixes the generation of the libtool script in cross-compiling environments

[Otavio Salvador]

From: Mario Domenech Goulart <mario at ossystems.com.br>

Generates the libtool file prefixed by ${host_alias} when it is set.
This is required in cross compiling environments (such as OpenEmbedded).
