David E. O'Brien 6da9f52720 * Remove the Linux -dynamic-linker specification from the `ld' execution.
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.
