source: configure @ e1e5bd6

Last change on this file since e1e5bd6 was 1de945b, checked in by dequis <dx@…>, at 2018-03-19T15:39:57Z

configure: Add -Wformat -Werror=format-security to default CFLAGS

Matches debian build scripts.

Also expands the condition to gcc or clang. I'd rather remove this,
apparently it exists because some opensolaris compiler didn't have -Wall
which seems absurd to me, but whatever.

Property mode set to 100755
