Extended Description

I just recompiled sac2c and the stdlib from scratch, under sac2c-follow
on Ubuntu 14.04 LTS. 
At this point, I am unable to compile anything that uses the standard
library:
ls /usr/local/libexec/sac2c/18614
comslc  ctest          libsac2c.so  sac2c-p  saccc                      tree
csima   libsac2c.d.so  sac2c        sac2tex  sacpolylibisnullintersect
csimt   libsac2c.p.so  sac2c-d      sac4c    sacprapolyhedral
sac@rattler:~/sac/testsuite/optimizations/awlf$ sac2c time2code.sac
  MT_MODE = 0 in target, forcing -numthreads to 1.
**  1: Loading SAC program ...

compilation failed while Loading SAC program.
sac@rattler:~/sac/testsuite/optimizations/awlf$ ls /usr/local/libexec/sac2c/18614/tree/host/
libsacpreludeTree.so
I see that there is nothing under tree/host except the sacprelude, so
the abort makes sense. 
I looked for some help on the sac-home web site, here:
http://www.sac-home.org/index.php?p=.%2F55_Download%2F41_Installation%2F41_Trouble_Shooting
cat  $SAC2CBASE/sac2crc
# Circumvent ubuntu linker problem.
target seq:
CFLAGS += " --Wl,--no-as-needed "
There is an empty .sac2crc in /home/sac.
I am guessing something is wrong with the install of the generated
stdlib. 
sudo make install
for the stdlib shows, in part, this:
Making install for target mt_pth

sac@rattler:~/sac/testsuite/optimizations/awlf$ sac2c-d -V
sac2c v1.00-beta (Haggis And Apple)
 developer rev 18614
Eventually, I did a .configure in the stdlib before building
and installing the stdlib. That resolved the above problem, 
but things then die in the linker, as noted in an earlier bug report.
This strikes me as something that is going to break a lot
of attempts to work with sac2c. Perhaps the makefile
can be fancied up so that it detects when sac2c has been changed,
and force a rerun of configure, or else abort with a suitable
error message?
