LIBC_TRY_TEST_CC_OPTION is defined with LIBC_TRY_CC_OPTION:
dnl Test a compiler option or options with an empty input file.
dnl LIBC_TRY_CC_OPTION([options], [action-if-true], [action-if-false])
AC_DEFUN([LIBC_TRY_CC_OPTION],
[AS_IF([AC_TRY_COMMAND([${CC-cc} $1 -xc /dev/null -S -o /dev/null])],
[$2], [$3])])
which passes -S to compiler. Unlike gcc, when -c is also passed to clang
20, we get
configure:7838: clang -c -Werror -fsemantic-interposition -xc /dev/null -S -o /dev/null
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
Don't pass -c to LIBC_TRY_TEST_CC_OPTION since -c isn't needed.
This fixes BZ #33318.
