Martijn Dekker dd0d03b973 Eliminate LDFLAGS hack to compile on certain OSs 
Instead, we now link to the libm system math library where needed
by adding -lm to the relevant compile commands in the Mamfiles.
This is not needed on every system but never does any harm.

(This adds more custom edits to the Mamfiles, which were originally
generated from the nmake Makefiles. This takes us further from
restoring nmake, but that already wasn't going to happen anyway,
due to its many problems... the path forward will be to translate
the Mamfiles to some other, current make system such as GNU make.)

bin/package, src/cmd/INIT/package.sh:
- Remove LDFLAGS=-lm hack for DragonFly BSD, NetBSD and Solaris.

src/cmd/builtin/Mamfile,
src/cmd/ksh93/Mamfile,
src/lib/libdll/Mamfile:
- Add -lm where linking failed on any of the three mentioned OSs.

src/lib/libdll/features/dll:
- In the output test program, add missing #include <math.h>, fixing
  unknown identifier errors on NetBSD (ldexp, ldexpl).

src/cmd/builtin/features/pty:
- Add missing #include <stdio.h> to make printf work on all systems
  (this is just a feature test, no need to bother with sfio here).

src/lib/libast/features/stdio:
- Undef __FILE_T to avoid interference from system headers on QNX.
  (There are still other problems preventing a build on QNX 6.5.0.
  The shipped version of gcc seems to be broken.)
