When building the U-Boot tools for non-ELF platforms (such as Blackfin FLAT), since commit 79fc0c5f498c3982aa4740c273ab1a9255063d9c ("tools/env: cross-compile fw_printenv without setting HOSTCC"), the build fails because it tries to strip a FLAT binary, which does not make sense.
This commit solves this by changing the stripping logic in tools/env/Makefile to be similar to the one in tools/Makefile. This logic continues to apply strip to the final binary, but does not abort the build if it fails, and does the stripping in place on the final binary. This allows the logic to work fine if stripping doesn't work, as it leaves the final binary untouched.

An improved solution would be to be able to override STRIP completely by setting it to /bin/true, but the main Makefile enforces STRIP = $(CROSS_COMPILE)strip.
