There is no such symbol in Buildroot.
Also, backtrace in uClibc-ng depends on support for shared libraries:
https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/tree/extra/Configs/Config.in#n2286
Can you have a further look and resend a fixed-up patch, please?
Also, we do have a standalone package that provides libbacktrace, and
which was not added so long ago. Does that package not provide what you
need?
Regards,
Yann E. MORIN.

I also forgot to state that uClibc-ng builds libubacktrace, not
libbactrace, so applications would need to have special handling to
explicitly load libubacktrace anyway...

Hi Yann,
Regarding the libbacktrace, in my application, I need to link the *execinfo.h
*file that is included in the uClibc-ng toolchain when the build
configuration includes UCLIBC_HAS_BACKTRACE. Because of this, I need to
build the entire libubacktrace in the uClibc-ng.
Thanks
