Wouldn't this cause build that use "-Os" (or -O3) to be forced to use "-O2"
for this package?
Using -Os makes for serious flash space savings on the MIPS settop boxes, we
found that the code generated with -Os isn't just smaller, but it compresses
into a much smaller filesystem than -O2 generated files. There appears to be
some synergy there between the compression algorithm (gzip or lzo) and the
code as generated with that option.

The build error (_FORTIFY_SOURCE=2 with -O0)
"warning _FORTIFY_SOURCE requires compiling with optimization (-O)"
