Check whether the given FLAG works with the linker or gives an error. (Warnings, however, are ignored)

ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on success/failure.

If EXTRA-FLAGS is defined, it is added to the linker’s default flags when the check is done. The check is thus made with the flags: "LDFLAGS EXTRA-FLAGS FLAG". This can for example be used to force the linker to issue an error when a bad flag is given.

INPUT gives an alternative input source to AC_LINK_IFELSE.

NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG.
