Luckly our `ld' knows the name of our dynamic linker and DTRT. * Remove the DECpaq shared libs from the standard search dir as linking with them gives unresolved symbols. Thus we'll use the .a's for now. * Add the symbols __errno_location, __ieee_get_fp_control, and __ieee_set_fp_control (mapped to native interfaces) to the static Compaq Portable Math Library. Thus all symbols are resolved. This allows `CC=ccc' to build fully native FreeBSD Alpha binaries.
