Subject: b43-asm: fix compile error: undefined reference to `yydebug'
X-Git-Tag: b43-fwcutter-018~4
X-Git-Url: https://jxself.org/git/?p=b43-tools.git;a=commitdiff_plain;h=62ac5a230d3e0d3bf92d1d4a1ce0a82189010e86

b43-asm: fix compile error: undefined reference to `yydebug'

With bison 2.7 YYDEBUG will be set to 0 if it was not set, then #ifdef
YYDEBUG returns true, but bison 2.7 treets YYDEBUG 0 as not set.

This fixes the following error:
obj/main.o: In function `main':
main.c:(.text.startup+0xaf): undefined reference to `yydebug'
collect2: error: ld returned 1 exit status
