Can you try narrow down which of your (many) CFLAGS seems to cause it?

I can't make any sense of this bug report.

CC/CFLAGS/LDFLAGS provided in comment 0 do not match the values that appear in the build log or the emerge --info output in comment 1.

Please provide exact instructions to reproduce the problem.
