libmultipath does not compile against glibc 2.34

[Uglymotha]

From glibc 2.34 changelog:

• When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, PTHREAD_STACK_MIN is no longer constant and is redefined to sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register sets for modern architectural features like Arm SVE.

Result is a type mismatch error in libmultipath/util.c, unsigned long int (size_t) vs unsigned int on line 226: if (stacksize < PTHREAD_STACK_MIN)

changing stacksize to be long int fixes the issue, but not sure if thats a desirable solution.
