[RFC PATCH Fortran] make enum_9/10.f90 testcases work under FreeBSD ARM

[Andreas Tobler]

Hi,

I have here a possible way to make the enum_9.f90 and the enum_10.f90 
work under arm*-*-freebsd*. The solution for enum_9.f90 is straight 
forward. But the one for enum_10.f90 requires a reordering of the 
dg-additional-sources line. This I do not understand yet, but maybe one 
of you does.

If I have the original ordering and change the dg-options to check on 
'target arm_eabi' I get strange compilation errors:

---
/build/gcc/obj_gcc_armv6/gcc/testsuite/gfortran/../../gfortran 
-B/build/gcc/obj_gcc_armv6/gcc/testsuite/gfortran/../../ 
-B/build/gcc/obj_gcc_armv6/armv6-unknown-freebsd11.0/./libgfortran/ 
-fno-diagnostics-show-caret -fdiagnostics-color=never ./enum_10.c -c -o 
arm_eabi89728.o arm_eabi89728.c^M
gfortran: fatal error: cannot specify -o with -c, -S or -E with multiple 
files^M
compilation terminated.^M
---

The -c comes after the enum_10.c ....

Attached the solution which makes the tests pass. I tested them under 
FreeBSD armv6-*-freebsd11.0 and x86_64-unknown-freebsd11.0. Also under 
x86_64-unknown-linux-gnu. All PASS.

Would this be ok for trunk?

TIA,
Andreas

	* gfortran.dg/enum_9.f90: Replace arm*-*-linux* with arm_eabi.
	* gfortran.dg/enum_10.f90: Likewise. Reorder dg-additional-sources.
