Peter Korsgaard c129606f4c gcc: fix 4.9.2 build with C++ and !wchar
The libcilk library (used on x86/x86-64 when building with C++ support)
unconditionally uses WCHAR_MIN / WCHAR_MAX, causing build issues with uClibc
when configured without wchar support.

[PATCH] cilk: fix build without wchar
When building against uClibc with wchar support disabled, WCHAR_MIN and
WCHAR_MAX are not defined leading to compilation errors.
Fix it by only including the wchar code if available.
