[Buildroot] [PATCH 1/1] Makefile: delete debug libs when debug is not enabled

[Danomi Manchego]

Some toolchains, like the Linaro gcc7 toolchains, now install libstdc++ debug
library symbols to /lib/debug, which can be as large as the library itself.
This commit removes the extra debug content if debugging is not enabled.
