collect2: error: ld returned 1 exit status
Makefile:42: recipe for target 'btt' failed

2)
git/blkiomon.c:216: undefined reference to `rb_insert_color'
collect2: error: ld returned 1 exit status
Makefile:27: recipe for target 'blkparse' failed

3)
ld: rbtree.o: invalid string offset 128 >= 125 for section `.strtab'

4)
btreplay.o: file not recognized: File truncated
collect2: error: ld returned 1 exit status
