[distcc] AIX patches

[Stuart D. Gathman]

I got distcc compiled and installed on AIX with an RPM spec that also 
works on Linux.  aix-4.1.5 is missing setenv.  I tried adding 
HAVE_SETENV to config.h.in and setenv to AC_CHECK_FUNCS in configure.ac, 
however, this did not cause configure to check for setenv.  I don't 
pretend to know how autoconfigure works, so I just made the patch 
conditional.

%description
distcc is a program to distribute compilation of C or C++ code across several
machines on a network. distcc should always generate the same results as a
local compile, is simple to install and use, and is often two or more times
faster than a local compile.

distcc does not require all machines to share a filesystem, have synchronized
clocks, or to have the same libraries or header files installed. Machines can
be running different operating systems, as long as they have compatible binary
formats or cross-compilers.

Install distcc if you have two or more networked computers and want to
speed up compiles.
