Set F_VFP_FLOAT for any binary not using FPA instructions

[Nick Clifton <nickc at cambridge dot redhat dot com>]

Hi Richard,

  Any objections to my applying the following patch ?  It changes the
  logic for setting the F_VFP_FLOAT flag in arm-elf binaries so that
  it is set for any binary that has been created without enabling FPA
  instructions - even binaries that have been assembled with the
  -mno-fpu switch.  This is the change from the previous behavior
  where assembling with -mno-fpu would not set the VFP flag.

  The reason for this change to get around the problem of compiling
  source files with the gcc switches "-mcpu=xscale -msoft-float".
  Although the soft-float flag is redundant, specifying it passes the
  -mno-fpu flag to the assembler, which then marks the binaries as
  using FPA instructions.  This then prevents the object file from
  being linked with other arm or xscale binaries, which by default are
  marked as using VFP instructions.

  It also has the side effect of making the code agree with the
  comment above it. :-)

Cheers
        Nick
