Revert "kbuild: strip generated symbols from *.ko"
This reverts commitad7a953c52. And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL")9bb482476cThese stripping patches has caused a set of issues: 1) People have reported compatibility issues with binutils due to lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2 Reported by: Wenji 2) ccache and distcc no longer works as expeced Reported by: Ted, Roland, + others 3) The installed modules increased a lot in size Reported by: Ted, Davej + others Reported-by: Wenji Huang <wenji.huang@oracle.com> Reported-by: "Theodore Ts'o" <tytso@mit.edu> Reported-by: Dave Jones <davej@redhat.com> Reported-by: Roland McGrath <roland@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
