Typo in the variable name, which means it wasn't used at all. If it had
been used, you would have spotted some build issues.

This line is not needed, since HOST_CONFIGURE_OPTS already contains
LDFLAGS="$(HOST_LDFLAGS)". However, I had to pass
CXXFLAGS="$(HOST_CXXFLAGS) -fPIC" to make the thing build.

Having two lines is not needed, building the "shared" target is
sufficient.

Using the "install" target is sufficient, so I've used that instead.

Since extract is the first step, we usually put this before the
build/install commands.

I've fixed up those issues and applied. Thanks!
