[PATCH] configure: Use -Werror=unknown-warning-option in later cross tests

[Martin Storsjo]

Previously, if detected, the option was added to EXTRACROSSFLAGS,
which isn't taken into use in later WINE_TRY_CROSSCFLAGS tests.

Signed-off-by: Martin Storsjo <martin(a)martin.st>

Alternatively, should WINE_TRY_CROSSCFLAGS automatically use
all of EXTRACROSSFLAGS?
