+
+**Fix cross-compile configure failures in diffutils, grep, coreutils, tar, findutils**
+
+### Changes:
+- Fixed `010-diffutils.sh`: Added `gl_cv_func_strcasecmp_works=yes` cache variable
+  to prevent "cannot run test program while cross compiling" error on strcasecmp check
+- Fixed `014-grep.sh`: Added `gl_cv_func_strcasecmp_works=yes` and
+  `gl_cv_func_fnmatch_gnu=yes` (same strcasecmp issue as diffutils)
+- Fixed `009-coreutils.sh`: Added `gl_cv_func_working_strerror=yes` and
+  `ac_cv_func_strnlen_working=yes` (strerror/strnlen runtime checks fail cross-compile)
+- Fixed `019-tar.sh`: Added `ac_cv_func_strnlen_working=yes`
+- Fixed `012-findutils.sh`: Added `gl_cv_func_fnmatch_gnu=yes`
+- Fixed `toolchain/bootstrap.sh`: Replaced `su -l lfs -c` with `env -i su lfs -s /bin/bash -c`
+  to avoid lfs .bash_profile's `exec env -i /bin/bash` swallowing the build command
+
+### Plan deviation/changes:
+- None
+
+### What is missing/needs polish:
+- None
