[Fortran - trunk, committed] Use auxiliary archives to solve excessive command line lengths with libtool (libf2c).

[Toon Moene <toon at moene dot indiv dot nluug dot nl>]

L.S.,

This is essentially the patch [attached] that David Edelsohn proposed to
solve the problem mentioned in the subject of this mail, which occurred
specifically on AIX with its multilibbing.

Bootstrapped, checked [Fortran only] and installed on
alphaev6-unknown-linux-gnu because I couldn't get several libf2c/libF77
functions compiled on i686 due to internal errors in simplify_gen_sub of
simplify_rtx.c.

Thanks, David !
