Subject: [PATCH] Don't use default CFLAGS, CXXFLAGS from autotools

Before this commit, autotools will inject `-g -O2` to debug build
(`--enable-debug=yes`) and rendering the result binary useless. This
commit fixes it.
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.70/html_node/C_002b_002b-Compiler.html

Closes #14032.
