Have you looked at:
http://cgit.openembedded.org/cgit.cgi/meta-openembedded/tree/meta-oe/recipes-devtools/xerces-c/xerces-c_3.1.4.bb?h=master

Sure set
B = "${S}"

Though, I'd rather suggest trying to get the library to build
out-of-tree. If you can get that going, it'll be better in the long run.

Cheers,
Anders
