undefined reference to `psiginfo'

[gardar]

I'm trying build ioctl on a ancient buildroot (BR2_GCC_VERSION="4.4.1" / BR2_UCLIBC_VERSION_STRING="0.9.32.1") but it fails with the following error:

arm-buildroot-linux-uclibcgnueabi-gcc -Wall   -c -MMD -c -o ioctl.o ioctl.c
ioctl.c: In function ‘sighandler’:
ioctl.c:48: warning: implicit declaration of function ‘psiginfo’
arm-buildroot-linux-uclibcgnueabi-gcc   ioctl.o ioctls_list_empty.o   -o ioctl
ioctl.o: In function `sighandler':
ioctl.c:(.text+0x60): undefined reference to `psiginfo'
collect2: ld returned 1 exit status
make[1]: *** [ioctl] Error 1

To work around the issue I commented out:
psiginfo(pinfo, "ioctl returned with signal");
and added:
fprintf(stderr, "ioctl returned with signal %d", signum);
which is not ideal...

Any ideas on how I can make psiginfo work?

If you find the correct macro to know if uclibc has been compiled with psiginfo, I could include it.
