The QEMU configure script incorrectly assumes SSP is supported by the toolchain in some cases where the compiler accepts -fstack-protector* flags but the C library does not provide the necessary __stack_chk_*() functions. Even though a full compile and link test is performed by the script, this is done with a code fragment which does not actually meet any of the conditions required to cause the compiler to emit canary code when the -fstack-protector-strong variant is used. As no compile or link failure occurs in this case, a false positive is generated and a subsequent error is seen when the probe for pthreads is performed. The fix consists in patching the configure script to use a more appropriate test program for the SSP support checks.
