In automake files, the check_PROGRAMS variable lists programs that need to be
build for testing, and TESTS lists the programs that need to be run.

The libbacktrace/Makefile.am uses a shortcut:
...
TESTS = $(check_PROGRAMS)
...
to make sure that each program added with:
...
check_PROGRAMS += foo

However, for the allocfail.sh test, we need allocfail to be build and
allocfail.sh to be run:
...
check_PROGRAMS += allocfail
TESTS += allocfail.sh
...
but the shortcut causes allocfail also to be run, which is not required.

Fix this by removing the short-cut, allowing check_PROGRAMS to retain its
original semantics, and introducing a variable BUILDTESTS for programs that
need to be both build and run.

When generating xcoff_%.c, the last command is a sed command.  In case of a
sed failure, this will leave an incomplete file, which will appear as up to
date to make, so consequently it will not be regenerated.  Fix this by
sedding into a temporary file instead.

Also, use $< to access the prerequisite xcoff.c, instead of spelling out the
file name once more.
