[committed] Fix lto build if WCONTINUED is not defined (PR lto/60571)

[Jakub Jelinek]

Hi!

WCONTINUED is (recent) Linux specific, so it doesn't have to be defined
on other hosts, or could be missing even on older Linux distros (e.g. glibc
2.3.2 doesn't have it).

Fixed thusly, committed as obvious.

        Fix formatting.
