OK, I can rename these to
#define PRINTSTR(x) STR(x)
#define STR(x) #x

Since this Library is replacement implementation of
ArmPlatformPkg/PlatformPei/PlatformPeiLib.inf,
Couldn't we use the same GUID ?

Actually I had submitted a patch is BaseTools for this:
https://edk2.groups.io/g/devel/message/53146
This patch makes use of that BaseTools patch.
But the BaseTools patch was not accepted because that is Linux specific.
Still these changes don't cause any negative affect.
Without BaseTools patch, empty string would be printed.
