>Description:

Building parallel/mpi-ch results in:

mpe2tmp.o: In function `dummy_subroutine':
check_callstack.c:(.text+0x11): undefined reference to `backtrace'
/home/pkgbulk/c/obj/parallel/mpi-ch/work/mpich2-1.4.1p1/src/mpe2/lib/libmpe_nompi.a(iterator.no):
 In function `MPE_CallStack_iteratorInit':
iterator.c:(.text+0x34): undefined reference to `backtrace_symbols_fd'
*** Error code 1

This is because it finds <execinfo.h> but doesn't notice or check that
you need -lexecinfo to use it.

I fixed the makefile so it no longer keeps going after the failure.

>How-To-Repeat:

as above

>Fix:

In src/mpe2/src/callstack, and also src/mpe2/src/logging, add autoconf
glop to check for -lexecinfo, and hack the makefiles to use it.
