HOST_WIDE_INT_PRINT_UNSIGNED must be separated from adjacent string literals by a space — required by C99 and enforced by newer compilers. Fixes build errors when compiling xilinx-gcc with a host GCC >= 12. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
HOST_WIDE_INT_PRINT_UNSIGNEDingcc/config/microblaze/microblaze.h(2 sites) andgcc/defaults.h(1 site).Modern GCC (≥12) requires a space between a macro that expands to a string literal and an adjacent string literal. Without the space the preprocessor emits a warning (and some compilers error). The fix is purely whitespace — no functional change.
