a malloc. The signal handler creates a thread which requires a malloc...
For now, the only thing to do is to block signals. When we move user
pthreads to use the kernel threads, mutexes will be implemented in kernel
space and then malloc can revert.
This fixes bugs in the manual handling. abs.[cS] was handled too
specially and the wrong (.c) variant for each of div.[cS], labs.[cS]
and ldiv.[cS] was added to SRCS. This caused the .c variant to be
used if `depend' was made and the .S version to be used otherwise.

Various cleanup from Keith Bostic
Reinstate calloc() as a separate funtion, in its own source/object file.
leave the manpage integrated with malloc.3 and friends. Too many things
were broken in this respect.

implement (better) falback code inside srandomdev() itself.
Change return type from int to void (binary compatibility surprisely
achieved). Userland code will be changed soon.
Malloc cannot use pthread_mutex_init() to initialize a mutex because
the mutex initialization process does a malloc!
libc_r internals skip the malloc and assign an initializer to a static
structure and point the opaque type (pthread_mutex_t in this case) to
that structure. This is done on the assumption that the mutex will never
be destroyed. This style of initialization is only valid inside libc_r
because the structure that is assigned is opaque to the user.
This fix allows a simple program to get to main() again. 8-)
so that all these makefiles can be used to build libc_r too.
Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.
Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.
Back out a dubious Lite2 change to "optimise" getcwd() to look at $PWD
because it's potentially dangerous (think: symlink races). Move
realpath() back to it's original location, and remove getcwd_physical()
by renaming it back to getcwd() and zapping the original getcwd wrapper.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
