tests: skip fcdemo checks when $FC cannot compile fortran90.

Avoid spurious fcdemo failures when Autoconf picks f77 or
similar for a fortran90 compiler.
* tests/testsuite.at (LT_AT_TAG): Using FC and FCFLAGS from make
TESTS_ENVIRONMENT, check that we really can compile fortran90
or else skip.

configury: use $(SED) where input does not end in newline.

On Solaris machines the system sed does not process the last
line of input unless it ends with a newline, which means it
cannot be used to massage the output of git-version-gen, because
it deliberately omits the terminating newline.
* Makefile.am (rebuild): Use the sed command found by configure,
which has a better chance of working properly than the first sed
on PATH.

maint: use $SED and $GREP, not sed and grep in all scripts.

Choosing between hardcoding a tool's name, or using the shell

optimisation.

testsuite: with SunStudio12.x f77, don't fail on system symbols

Modern SunStudio f77 is just a wrapper for f90, which
explains why current master fails these test groups with:

 Undefined	first referenced
  symbol  	    in file
 __f90_slw_ch      .libs/foof2.o
 __f90_sslw        .libs/foof2.o
 __f90_eslw        .libs/foof2.o
 ld: fatal: symbol referencing errors. No output written to
.libs/libfoo2.so.0.0.0

So we allow some undefined symbols in the libraries, which are
resolved by the $(FLIBS) added to the final binaries in the tests.
This seems like the simpler, and less error inducing solution to
me (compared to adding $(FLIBS) to every library LDFLAGS line).
* tests/f77demo.at (libfoo_la_LDFLAGS, libfoo2_la_LDFLAGS)
(libfoo3_la_LDFLAGS, libmix_la_LDFLAGS): Remove -no-undefined
flag.
* tests/fcdemo.at: Likewise.

tests: gcj cannot reliably compile directly to .o from .java

Some 4.3.x and 4.4.x releases of gcj insert a spurious 'dummy'
symbol into every object file when compiling directly from .java
to .o:
* tests/convenience.at (GCJ): make .class files from .java
sources first, and then compile those to native objects. This
works around http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42143
