Macro AST_PKG_CONFIG_CHECK to use chkconfig AST_PKG_CONFIG_CHECK: Similar to AST_EXT_LIB_CHECK, but simply uses pkg-config data. This simple version only uses pkg-config(1)'s tests. This commit also uses the macro to test for GTK2 and GMIME (instead of the current direct usage of pkg-config).

Build System: Strip '-std=c99' from CFLAGS provided by libraries. Asterisk requires GNU C extensions. On some systems certain libraries may incorrectly push -std=c99 into CFLAGS, thus breaking the build. This change causes that flag to be stripped so the Asterisk build is not broken by those libraries. This change is made for both pkgconfig and tool based libraries.
