Cheesy kconfig stuff:
- silent/quiet/verbose build:
- ct-ng by default only prints quit messages, such as "CC xxx",
- if using V=0, nothing is printed,
- if using V=1, the full command lines are printed,
- other values are indeterminate,
- should help in debugging the kconfig stuff;
- complete kconfig/{,m}conf generation:
- fully dynamic dependencies on source files,
- compilation of .c into .o, then linking (instead of direct linking),
- VPATH usage when not --local;
Typo + a coment moved.

    10 

    11 On sh[34]-linux, memset function does not work if 2nd argument is negative

    12 and 3rd argument is greater than 12.

    13 for example, memset(ptr, "\xda", 20) sets 0xff instead of 0xda.

    14  

    15 Attached patch fixes this problem.

    16  

    17 	* sysdeps/sh/memset.S (memset): Correct 2nd argument handling.
