[Click] Tiny fix for etc/pkg-userlevel.mk

[Pavlos Papageorgiou]

Hi Eddie,

I suggest the following fix in click/etc/pkg-userlevel.mk.

My build fails when:

	- I build a package (click already built successfully)

		and

	- I override CXX when I invoke the package makefile
	  (I build userlevel and linuxmodule in one shot)

In pkg-userlevel the -fPIC flag is appended to CXX instead
of CXXFLAGS and as a result disappears when someone overrides
CXX. Adding -fPIC to the overridden CXX does not work either,
because pkg-linuxmodule.mk uses the same CXX variable and
tries to use -fPIC for the kernel, where of course it fails.

Thanks,
Pavlos
