+Description: Add strtonum() to generated conftest.awk
+ conftest.awk uses the strtonum() function of GNU Awk to check for a linker that
+ supports the "-z relro" option.
+ .
+ This patch adds the pure awk implementation of strtonum() found in
+ awklib/eg/lib/strtonum.awk in GNU Awk to enable conftest.awk to run on other
+ awk implementations.
