[Buildroot] [PATCH 1/1] package/libuhttpd: depends on gcc >= 4.9

[Fabrice Fontaine]

Add a dependency on gcc >= 4.9 to avoid the following build failure
with gcc 4.8.3 raised since bump to version 3.14.1 in commit
61797c52f5deef2cb67e60cf075ca243078c8855 and
https://github.com/zhaojh329/libuhttpd/commit/ffdf7de3a4a1f5a62aa3814ac96e889958a30840:

/home/peko/autobuild/instance-1/output-1/build/libuhttpd-3.14.1/src/cgi.c:41:5: error: initializer element is not a constant expression [-Werror]
     {"accept", strlen("accept"), "HTTP_ACCEPT"},
     ^

It should be noted that upstream rejected a patch to remove -Werror:
https://github.com/zhaojh329/libuhttpd/pull/12
