Subject: Makefile: Add --exclude-libs ALL to avoid .dynsym
X-Git-Tag: v1.4~85
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6ed125a6027eea0f22b92d96d6fb538446fa94c0;p=platform%2Fkernel%2Fopensbi.git

Makefile: Add --exclude-libs ALL to avoid .dynsym

Since everything is statically linked, we don't need to expose symbols
for dynamic linking.

For a default build this saves about 2 KiB of useless read only data in
.dynsym, .dynstr, .hash, .gnu.hash sections.
