When setting ENABLE_FULL_DEBUG_SYMBOLS as environment variable make doesn't pick up its value (while it does for ZIP_DEBUGINFO_FILES):

$ export ENABLE_FULL_DEBUG_SYMBOLS=0
$ export ZIP_DEBUGINFO_FILES=0
$ echo $ENABLE_FULL_DEBUG_SYMBOLS $ZIP_DEBUGINFO_FILES
0 0
$ make jvmg1
INFO: ENABLE_FULL_DEBUG_SYMBOLS=1
INFO: /usr/bin/objcopy cmd found so will create .debuginfo files.
INFO: STRIP_POLICY=min_strip
INFO: ZIP_DEBUGINFO_FILES=0
Btw. make says that ZIP_DEBUGINFO_FILES is zero but it still zips the .debuginfo file.
