Currently there is a problem building packages that use *-config
scripts (for example gnupg), we are creating a
/bin/sh->/data/data/com.termux/files/usr/bin/sh symlink so that the
shebang for the scripts can be interpreted, but after
ecd214881a ("build-package: add new arg -c for "continue build"") the
symlink was deleted in termux_step_get_dependencies.
