 add clapack files

Adding two files that are part of clapack source
The clapack archive that can be downloaded at
  http://netlib.org/clapack/
contains a copy of f2c.  This copy is basically identical but it includes
two files which are missing in the source which was the base for the libf2c2
package.  Since the functions inside these files are used inside the test suite
of clapack the files were added here to avoid code duplication.

Add missing files also to makefile.u to get them built

 weak main__

Make MAIN__ a weak symbol

Make MAIN__ a weak symbol, to make sure that non-f2c binaries can link
against libraries created by it. Also make main() a weak symbol, just
in case, because we really don't want to override a C program's main
routine.

 format security sprintf
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

Squash potential buffer overflow noticed by GCC.  Note that even if
this is not an actual danger, a false positive can cause FTBFS in a
high security environment.

open.c: In function fk_open:
open.c:222:28: warning: %ld directive writing between 1 and 11 bytes into a region of size 5 [-Wformat-overflow=]
  (void) sprintf(nbuf,"fort.%ld",(long)n);
                            ^~~
open.c:222:22: note: directive argument in the range [-2147483648, 2147483647]
  (void) sprintf(nbuf,"fort.%ld",(long)n);

open.c:222:2: note: sprintf output between 7 and 17 bytes into a destination of size 10
  (void) sprintf(nbuf,"fort.%ld",(long)n);

 xintxx_t

Instead of casing off on architectures, use int/uint _ 16/32/64.

 f77_aloc type

Be consistent about type of F77_aloc().  Ultimately it calls
malloc(size_t) so just use size_t for the length.

See bugs.debian.org/748989 which says:

... research compiler tool-chain ... which permits extended reporting
on type inconsistencies at link time.

The original declarations can be reviewed here:

http://sources.debian.net/src/libf2c2/20090411-2/f77_aloc.c?hl=14#L14
http://sources.debian.net/src/libf2c2/20090411-2/getenv_.c?hl=11#L11

It seems that the latter should be adjusted, replacing ftnlen by integer. One
may hope that the remaining bytes (for all systems with sizeof(short
int)<sizeof(int)) happen to be zero - but on big endian systems this should
yield some fun. (Not.)

 cross

The file makefile.u hard codes the build architecture ld, which needs
to be made substitutable for cross compilation.
