[Buildroot] [PATCH v2] uclibc: enable debug build option

[Peter Seiderer]

Set uClibc DODEBUG in case BR2_ENABLE_DEBUG is set.

Setting DODEBUG was removed with commit 70b7079d3797304fe3c9ba2941d3f446af3cea79
in Dec. 2013 because of build failures with the old uClibc (now replaced
with uClibc-ng), no build failure with raspberrypi3_defconfig and
BR2_ENABLE_DEBUG enabled.

  - fix 'DODEBUG=y' typo (spotted by Thomas Petazzoni)
