Hi all,

I recently moved to using GCC 6.1 and while building a toolchain for arm-none-eabi I got
some -Werror=parentheses errors while building gdb.

This patch fixes them. I think this is due to the way ALL_OBJSECTIONS is defined
(due to using ALL_OBJFILE_OSECTIONS):
#define ALL_OBJFILE_OSECTIONS(objfile, osect)   \
   for (osect = objfile->sections; osect < objfile->sections_end; osect++) \
     if (osect->the_bfd_section == NULL)                                 \
{ \
         /* Nothing. */                                                 \
} \
     else


so that dangling 'else' probably causes the alarm in GCC.

This patch fixes the -Werror errors for me and allows the build to finish successfully.

Is this ok to commit?

Thanks,
Kyrill
