Subject: Ignore undefined symbols for -mtls-dialect=gnu2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=15aebdbada54098787715448c94701f17033fc92;p=thirdparty%2Fglibc.git

Ignore undefined symbols for -mtls-dialect=gnu2

So it does not fail for arm config that defaults to -mtp=soft (which
issues a call to __aeabi_read_tp).
