             : PSP_BIOSBIN_SIZE=$(shell $(READELF_bootblock) -l $(PSP_ELF_FILE) | grep -A1 LOAD | tr -d '\n' | awk '{print $$5}')
             : else

             : endif
If you pass the wide option to readelf (-lW instead of -l), it will still be on a single line for the grep/awk commands.  Should work for both 32-bit and 64-bit cases.
