  cmake: Define STDC_HEADERS for regex in mingw toolchain

Defining STDC_HEADERS macro includes stdlib.h in regex.c which is
required for free, abort etc. function declarations. This fixes the
following compiler error with mingw clang.

regex.c:2042:3: error: call to undeclared library function 'free' with type
'void (void *)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
regex.c:2784:11: error: call to undeclared library function 'abort' with type
'void (void) __attribute__((noreturn))'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
