compilers: avoid -Wunused-value compiler warning in CLikeCompiler.has_type()
Otherwise, `CFLAGS='-Wall -Werror' meson build` can fail detection:
Running compile:
Working directory: ./project/build/meson-private/tmpk86bgc04
Code:
#include <sys/types.h>
void bar(void) {
sizeof(loff_t);
}
-----------
Command line: `cc ./project/build/meson-private/tmpk86bgc04/testfile.c -o ./project/build/meson-private/tmpk86bgc04/output.obj -c -Werror -Wall -D_FILE_OFFSET_BITS=64 -O0 -std=gnu99` -> 1
stderr:
./project/build/meson-private/tmpk86bgc04/testfile.c: In function 'bar':
./project/build/meson-private/tmpk86bgc04/testfile.c:3:13: error: statement with no effect [-Werror=unused-value]
3 | sizeof(loff_t);
| ^~~~~~
cc1: all warnings being treated as errors
-----------
Checking for type "loff_t" : NO
