the first question is:
why i get this rm failures? i served the config files and know the man of 
rm... this must work... "rm -rf xxx* xxx*" is mostly used but makes the 
failures i thought... (./Makefile ./libiberty/configure.lineno 
./config.cache)

the second:
LDFLAGS are green small animals that have big ears and pink hairs... no... i 
think tomorrow i know this... and do it by hand...

the last:
points to one....

thanks for the poky lifetime... greets
