glibc-2.3.2 nonportable .section declaration for empty sections

[Ralph Siemsen]

There is a problem building glibc-2.3.2 on platforms such as arm which
use the @ symbol as a comment character.  According to the info pages
for gas, in such cases the @ symbol is to be replaced with %.  However,
glibc fails to do so in include/libc-symbols.h:

#  define libc_freeres_ptr(decl) \
  __make_section_unallocated ("__libc_freeres_ptrs, \"aw\", @nobits") \

This leads to bad .section directives being generated all over the
glibc tree, and the assembler subsequently complains:

/tmp/ccHfHquJ.s: Assembler messages:
/tmp/ccHfHquJ.s:10: Warning: rest of line ignored; first ignored
character is `,'
/tmp/ccHfHquJ.s:12: Warning: rest of line ignored; first ignored
character is `,'

This problem is present in CVS HEAD as well.  Changing the @nobits to
%nobits solves the problem, although I suspect this would break the
built on other architectures.
