The manual says one thing, reality says another:

package/collectd/Config.in:comment "write_prometheus needs a toolchain w/ C++, host gcc >= 4.5"
package/cppcms/Config.in:comment "icu support needs a toolchain w/ gcc >= 4.8, host gcc >= 4.8"
package/icu/Config.in:comment "icu needs a toolchain w/ C++, wchar, threads, gcc >= 4.8, host gcc >= 4.8"
package/kodi/Config.in:comment "kodi needs python w/ .py modules, a uClibc or glibc toolchain w/ C++, locale, threads, wchar, dynamic library, gcc >= 4.8, host gcc >= 4.6"
package/mfgtools/Config.in.host:comment "mfgtools needs host gcc >= 4.8"
package/midori/Config.in:comment "midori needs libgtk3 and a glibc toolchain w/ C++, gcc >= 4.9, host gcc >= 4.8"
package/php/Config.ext:comment "intl support needs a toolchain w/ C++, wchar, threads, gcc >= 4.8, host gcc >= 4.8"
package/protobuf-c/Config.in:comment "protobuf-c needs a toolchain w/ C++, threads, host gcc >= 4.5"
package/python-mwscrape2slob/Config.in:comment "python-mwscrape2slob needs a toolchain w/ C++, gcc >= 4.8, host gcc >= 4.8"
package/python-pyicu/Config.in:comment "python-pyicu needs a toolchain w/ C++, gcc >= 4.8, host gcc >= 4.8"
package/python-slob/Config.in:comment "python-slob needs a toolchain w/ C++, gcc >= 4.8, host gcc >= 4.8"
package/qt5/qt5base/Config.in:comment "icu support needs a toolchain w/ gcc >= 4.8, host gcc >= 4.8"
package/qt5/qt5webkit/Config.in:comment "qt5webkit needs a toolchain w/ dynamic library, gcc >= 4.8, host gcc >= 4.8"
package/riemann-c-client/Config.in:comment "riemann-c-client needs a toolchain w/ C++, threads, host gcc >= 4.5"
package/webkitgtk/Config.in:comment "webkitgtk needs libgtk3 and a glibc toolchain w/ C++, gcc >= 4.9, host gcc >= 4.8"

I'm not sure why we would not add Config.in comment for dependencies on
the host toolchain. What's the reasoning for *not* adding such
dependencies ?

Best regards,

Thomas
