[SPEC] Workaround error with latest clang in 523.xalancbmk_r (#118)

xalan-c contains a latent error in a template that isn't instantiated,
which after llvm/llvm-project#90152 means
523.xalancbmk_r and 483.xalancbmk will now fail to build. We can workaround
it by setting -fdelayed-template-parsing.
