It gets linked to libgcc_s (shared lib) unless doing the trick I thought feasible of telling 'configure' that the linker does not support "as-needed". I found this reading their 'configure' script. We don't want nscd linked to libgcc because that would make glibc dependant on the previous gcc. This only happens on armv5tel, for the supported platforms. svn path=/nixpkgs/branches/stdenv-updates/; revision=24959

/* Fix for NIXPKGS-79: when doing host name lookups, when
|
|
nsswitch.conf contains a line like
|
|
|
|
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
|
|
|
|
don't return an error when mdns4_minimal can't be found. This
|
|
is a bug in Glibc: when a service can't be found, NSS should
|
|
continue to the next service unless "UNAVAIL=return" is set.
|
|
("NOTFOUND=return" refers to the service returning a NOTFOUND
|
|
error, not the service itself not being found.) The reason is
|
|
that the "status" variable (while initialised to UNAVAIL) is
|
|
outside of the loop that iterates over the services, the
|
|
"files" service sets status to NOTFOUND. So when the call to
|
|
find "mdns4_minimal" fails, "status" will still be NOTFOUND,
|
|
and it will return instead of continuing to "dns". Thus, the
|
|
line
|
|
|
|
hosts: mdns4_minimal [NOTFOUND=return] dns mdns4
|
|
|
|
does work because "status" will contain UNAVAIL after the
|
|
failure to find mdns4_minimal. */
