SOURCE BUG Duration: 59s

Subject

- add target hosttools (see make help) - rename check_gcc to check_cc and pass the CC to use as arg#1; peruse check_cc for HOSTCFLAGS - add and use check_strip - add checks for {,no-}whole-archive and {start,end}-group LD flags

SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): scripts/config/mkconfigs.c (2005-08-01 - 2006-10-05 arasi) uretilen bbconfigopts.h icine .config satirlarini kacissiz, ham newline'larla gömüyordu - gecerli C degildi, busybox'un kendi bb_mkdep araci bile parse edemiyordu (7d219aab7 ile duzeltildi, mkconfigs shell scripte cevrildi)
