Nice one, thanks! I downgraded my chroot libc to 2.9-25 and reproduced
the issue also. That libc has no _nss_files_parse_sgent, as expected:

$ objdump -T /lib/libc.so.6 | grep nss_files_parse
00096c60 g    DF .text 000002d0  GLIBC_PRIVATE _nss_files_parse_pwent
00095810 g    DF .text 000002f5  GLIBC_PRIVATE _nss_files_parse_grent
000d1c60 g    DF .text 000003d2  GLIBC_PRIVATE _nss_files_parse_spent

Is there a way to contact the build machine maintainers? Other than
hoping they read this thread?
