When BR2_STRIP is set to none, a dummy 'true' app is used instead of
strip utility. However, kexec package always requires a real strip
executable as it is used to generate intermediate files during the build
process.
If 'true' is used the build system runs the following command:
true --strip-debug -o purgatory/purgatory.ro purgatory/purgatory.ro.sym
which obviously doesn't do anything useful and the build later fails
with:
bin/bin-to-hex purgatory < purgatory/purgatory.ro > kexec/purgatory.c
/bin/sh: purgatory/purgatory.ro: No such file or directory
kexec/Makefile:7: recipe for target 'kexec/purgatory.c' failed
make[2]: *** [kexec/purgatory.c] Error 1
To resolve it always specify STRIP=$(CROSS_COMPILE)strip, regardless of
buildroot configuration.
