They are different, incompatible pthread implementations, yes.

libkse is the same code as what is installed as libpthread on other
architectures (i.e. M:N), but since it doesn't work on sparc it is not
not installed as libpthread (libthr or libc_r are depending on
version).

-pthread, not -lpthread.  But yes, libmap.conf or equivalent
mechanisms (see manpage).
