A GCC export should be able to tell more, but the warning should be harmless.

Objects/obmalloc.c says that the thread sanitizer is available from GCC 4.8, 
but for some reason it isn't on your system. This seems to be a bug in 
obmalloc.c:  The GCC 4.8.5 docs don't mention this attribute [1], while the 5.5 
docs do [2]

https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcc/Function-Attributes.html#Function-Attributes
[2] 
https://gcc.gnu.org/onlinedocs/gcc-5.5.0/gcc/Function-Attributes.html#Function-Attributes

There's a couple of releases between 4.8.5 and 5.5.0, I don't know which one 
introduces this function attribute. Once that version is know it should be 
fairly easy to provide a patch that only uses the attribute for new enough 
compilers.
