[LEDE-DEV] BUG: gcc build failure of lede-project HEAD for ath25

[Russell Senior]

Building lede-project HEAD, i.e.:

   $ git describe 
   reboot-98-g5b64e35

The interesting bits of diffconfig is:

   CONFIG_TARGET_ath25=y
   CONFIG_TARGET_ath25_Default=y
   CONFIG_TARGET_BOARD="ath25"
   CONFIG_DEVEL=y
   CONFIG_BUSYBOX_CUSTOM=y
   CONFIG_BUILD_LOG=y

I get a build failure in gcc.  The command line looks like this:

  make -j1 BUILD_LOG=1 IGNORE_ERRORS=m V=s

The tail of logs/toolchain/gcc/final/compile.txt looks like this:
