Since 4b0f891211
squid tries to find if latomic is needed through:
AC_SEARCH_LIBS([__atomic_load_8],[atomic],[ATOMICLIB="-latomic"],[])
However, this can fails on:
configure:21147: /home/fabrice/buildroot/output/host/bin/arc-buildroot-linux-gnu-g++ -o conftest -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -matomic -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -g conftest.cpp -latomic >&5
conftest.cpp:55:6: error: new declaration 'char __atomic_load_8()' ambiguates built-in declaration 'long long unsigned int __atomic_load_8(const volatile void*, int)' [-fpermissive]
char __atomic_load_8 ();
^~~~~~~~~~~~~~~
conftest.cpp: In function 'int main()':
conftest.cpp:59:25: error: too few arguments to function 'long long unsigned int __atomic_load_8(const volatile void*, int)'
return __atomic_load_8 ();
So add -latomic to LIBS if BR2_TOOLCHAIN_HAS_LIBATOMIC is set
