this still seems to be broken for a gdb trunk build, using GMP and MPFR system 
libraries:

linking gdb:

[...]
../gnulib/import/libgnu.a   -Lyes/lib -lmpfr -lgmp -lsource-highlight 
-lboost_regex  -lxxhash  -ldebuginfod   -ldl 
-Wl,--dynamic-list=/<<PKGBUILDDIR>>/gdb/proc-service.list
./libtool: line 5209: cd: yes/lib: No such file or directory
libtool: link: cannot determine absolute directory name of `yes/lib'
make[3]: *** [Makefile:2174: gdb] Error 1
make[3]: Leaving directory '/<<PKGBUILDDIR>>/build/default/gdb'

the toplevel config.log has:
