libtool cross compiling with heimdal

[Love Hörnquist Åstrand]

Hello,

I'm using libtool in Heimdal and have some questions about cross  
compiling.

What flags should I pass to libtool to make sure it picks up libraries  
to link with and .la files from the target's environment.

Today I use LDFLAGS="-XCClinker -B$pathtotargetroot/usr/lib", but  
then, that seems like a gross hack since I also have to patch up  
sys_lib_search_path

I could compile ld to use --sysroot, but then, how do I make sure  
that .la files are picked up from the target enviroment instead of the  
host enviroment.

Process to cross compile heimdal is documented here:

Thanks,
Love
