Change "export FC=foo" to "FC=foo ; export FC" and similar in scipy_sandbox

[sagetrac-drkirkby]

#10092 added 4 lines of code:

export FC="${SAGE_LOCAL}/bin/sage_fortran"
export F77="${SAGE_LOCAL}/bin/sage_fortran"
export F90="${SAGE_LOCAL}/bin/sage_fortran"
export F95="${SAGE_LOCAL}/bin/sage_fortran"

but using export and the variable name at the same time is not portable. For improved portability, which will work with any shell,

FC="${SAGE_LOCAL}/bin/sage_fortran"
export FC
F77="${SAGE_LOCAL}/bin/sage_fortran"
export F77
F90="${SAGE_LOCAL}/bin/sage_fortran"
export F90
F95="${SAGE_LOCAL}/bin/sage_fortran"
export F95

should work.

The revised package may be found here. I've checked it on my OpenSolaris machine, but also on fulvia where it failed before:
