[gfortran, doc] PR15478 Integrate gfortran build info in main docs

[Tobias Schlüter <tobias dot schlueter at physik dot uni-muenchen dot de>]

This patch moves gfortran's documentation closer GCC's documentation 
curing one of Joseph's issues from the PR:
---
The whole "Compiling and Testing" chapter should go away; binaries have 
a place to document them in install.texi, as do prerequisites such as GMP.
---
I removed that section and added the info concerning GMP to 
doc/install.texi.

	PR fortran/15478
	* doc/install.texi: Document GMP as prerequisite. Document
	--with-gmp and --with-gmp-dir configure options.
	* fortran/gfortran.texi: Remove section "Compiling and testing",

-Compiling gfortran requires the presence of GMP,
-the GNU Multiple Precision library version 4.0
-or better in order to do its arithmetic.
-Download @code{gmp} from your favorite GNU mirror,
-configure and compile it.  If your OS distributor provides prepackaged
-GMP libraries, you may also need the developent pacakges.
-
-If you do not have GMP installed in a standard system location, you may
-need to configure GCC with @option{--with-gmp} or @option{--with-gmp-dir}.
-
-Note: GMP is only required for the compiler itself.  Compiled fortran programs
-do not depend on the GMP library.

-@node Testing

-@cindex Test suite
-@cindex Testing
-
-The number of possible Fortran 95 programs is unlimited,
-and this means that gfortran has to correctly handle lots of possible inputs.
-Whenever you make any changes to the compiler,
-you should first test your change on a test program,
-then test your change against the gfortran test suite.
-In this way, we can be assured that once your fix has been made,
-the problem isn't re-introduced at some later time.
-
-The gfortran test suite is included in the gcc source distribution.
-
-We also encourage you to test gfortran on your own Fortran codes.
