I guess I do not understand then how your libtool comes to contain
SHELL=/bin/sh and mine has the correct SHELL=/usr/pkg/bin/pdksh

I think this should be fixed in the compiler specific transforms found
in pkgsrc/mk/wrapper/* the idea being that based on the compiler (or
other tool) in use, all args are converted to match what is needed.  I
am aware that these are currently incomplete, but have not understood
the entire infrastructure sufficiently yet to propose required fixes.

I'm not sure I follow the complex solution you suggest, but if the
only requirement is to remove the -xar argument, then
WRAPPER_TRANSFORM_CMDS+= rm:-xar would do that for you.

I'm not a make expert, so perhaps someone else could better answer the
other questions.
