[Buildroot] [PATCH] libsvgtiny: disable -Werror

glibc-2.20 includes some changes to the include/features.h file
introduced by this commit:

  https://sourceware.org/git/?p=glibc.git;a=commit;h=ade40b10ff5fa59a318cf55b9d8414b758e8df78

Those changes make libsvgtiny fail because some warnings are thrown and
the build system is using the -Werror option. We disable this to be able
to build it, or otherwise we will see errors like this one:

GPERF: src/colors.gperf
COMPILE: build-Linux-Linux-release-lib-static/src_colors.c
In file included from
/br/output/host/usr/mipsel-buildroot-linux-gnu/sysroot/usr/include/string.h:25:0,
		 from src/colors.gperf:16:
/br/output/host/usr/mipsel-buildroot-linux-gnu/sysroot/usr/include/features.h:148:3:
error: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use
_DEFAULT_SOURCE" [-Werror=cpp]

and this one:

In file included from src/colors.gperf:18:0:
/home/ldap/vriera/work/mips-buildroots/mips32/output/build/libsvgtiny-12121/src/svgtiny_internal.h:71:0:
error: "strndup" redefined [-Werror]
