4232f82668 Enforce overwritting SHLIBDIR
Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.

This makes /lib being populated again.

4cef7be5c3 Add reachover Makefiles for contrib/netbsd-tests/lib/librt
A variant of this code has been tested on amd64/i386 for some time by
EMC/Isilon on 10-STABLE/11-CURRENT. It builds on other architectures, but the
code will remain off until it's proven it works on virtual hardware or real
hardware on other architectures

  . Expose lgammal_r as a weak reference to lgamma_r for platforms
    where long double is mapped to double.

* src/e_lgammaf_r.c:
  . Fixed the Cygnus Support conversion of e_lgamma_r.c to float.
    This includes the generation of new polynomial and rational
    approximations with fewer terms.  For each approximation, include
    a comment on an estimate of the accuracy over the relevant domain.
  . Use integer literal constants instead of real literal constants.
    Let compiler(s) do the job of conversion to the appropriate type.
    This allows the removal of several explicit casts of double values
    to float.

* src/e_lgammal.c:
  . Wrapper for lgammal() about lgammal_r().

  . For architectures where double and long double are the same
    floating point format, use weak references to map erfl to
    erf and ercl to erfc.

4758b87596 Add stub implementations of the missing C++11 math functions.
These are weak and so can be replaced by other versions in applications
that choose to do so, and will give a linker warning when used so that
applications that rely on the extra precision can avoid them.

Note that since the C/C++ specs only guarantee that long double has
precision equal to double, code that actually relies on these functions
having greater precision is unportable at best and broken at worst.

7dbbb6dde3 Fix some regressions caused by the switch from gcc to clang. The fixes
are workarounds for various symptoms of the problem described in clang
bugs 3929, 8100, 8241, 10409, and 12958.

The regression tests did their job: they failed, someone brought it
up on the mailing lists, and then the issue got ignored for 6 months.
Oops. There may still be some regressions for functions we don't have
test coverage for yet.

12188b77a2 The cexp() and {,c}{cos,sin}h functions all need to be able to compute
exp(x) scaled down by some factor, and the challenge is doing this
accurately when exp(x) would overflow.  This change replaces all of
the tricks we've been using with common __ldexp_exp() and
__ldexp_cexp() routines that handle all the scaling.

bde plans to improve on this further by moving the guts of exp() into
k_exp.c and handling the scaling in a more direct manner.  But the
current approach is simple and adequate for now.

6684d0ace3 Sort the .PATH entries to give a more reasonable order of precedence:
1. architecture-specific files
     2. long double format-specific files
     3. bsdsrc
     4. src
     5. man
The original order was virtually the opposite of this.

This should not cause any functional changes at this time. The
difference is only significant when one wants to override, say, a
generic foo.c with a more specialized foo.c (as opposed to foo.S).
