That's not entirely true since sparc_md_end will set the correct architecture:
(gdb) bt
#0 bfd_default_set_arch_mach (abfd=0x769d20, arch=<optimized out>,
mach=<optimized out>) at /home/eric/cvs/binutils-gdb/bfd/archures.c:976
#1 0x0000000000428774 in sparc_md_end ()
at /home/eric/cvs/binutils-gdb/gas/config/tc-sparc.c:1187
#2 0x0000000000403da6 in main (argc=2, argv=0x754350)
at /home/eric/cvs/binutils-gdb/gas/as.c:1288
(gdb) p *stdoutput->arch_info
$7 = {bits_per_word = 64, bits_per_address = 64, bits_per_byte = 8,
arch = bfd_arch_sparc, mach = 7, arch_name = 0x514dd3 "sparc",
printable_name = 0x519135 "sparc:v9", section_align_power = 3,
the_default = 0, compatible = 0x433f90 <bfd_default_compatible>,
scan = 0x433b90 <bfd_default_scan>, fill = 0x433f60 <bfd_arch_default_fill>,
next = 0x519440 <arch_info_struct+480>}
but it's indeed too late for the .dc.a directive.
