[Bug releng/32523] make stap buildable with clang/clang++

[Денис Пронин]

Hello,

The issue is in *-Werror* flag that is passed to the compiler through 
*automake + autoconf* utilities. clang catches some warnings-as-errors 
and fails the compilation process

*-Werror* is often a killer of compilation. I would consider getting rid 
of it at all or pass *CXXFLAGS=-Wno-error* to the *./configure* script. 
*-Werror* is a notorious flag that does nothing useful, from my point of 
view, but ensures for the compilation to be clean from warnings

Thank you
