Subject: tor: link with libatomic when needed
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b1da7a8aed6a12eeb9ad7f3870a79be859e137f0;p=buildroot.git

tor: link with libatomic when needed

The following error occurs on architectures required to use gcc
libatomic for atomic intrinsics:

sparc-buildroot-linux-uclibc/sysroot/lib/libatomic.so.1: error adding symbols: DSO missing from command line

This is for example the case on sparcv8 32 bit.

Fixes:
