How about realizing this with the patch below?
I like it in general, but:
+ -fsanitize*)
+ echo -n "$cflag ";;
Why is that given special exception? IMHO, it is a developer specific
thing and people using our needed flags should make their own compiling
choices for all -f or -W like options.
-fsanitize is special. It is the only -f flag I know of that causes
additional libraries to be linked. If -fsanitize is treated in the same
way as other -f flags (filtered out) then ld complains about undefined
references:
$ ./configure 'CFLAGS=-fsanitize=address -fsanitize=pointer-compare
-fsanitize=pointer-subtract -fsanitize=leak -fsanitize=undefined'
'LDFLAGS= -fsanitize=address -fsanitize=pointer-compare
-fsanitize=pointer-subtract -fsanitize=leak -fsanitize=undefined'
$ make
