Lack of backtrace*() functions (they should be declared in execinfo,h)

I’m trying to build https://github.com/facebook/rocksdb. But getting this error execinfo.h: No such file or directory execinfo.h is a part of gnulib. For which, I cannot find a package on Alpine packages page.
Please add this this library as package or guide me through the build process.
