Add a BR2_NEEDS_GETTEXT option
When using an external toolchain that uses the glibc or eglibc C libraries, compiling a separate gettext and libintl is not needed and is even a source of confusion, causing build failures. These build failures are due to the fact that when libintl is compiled, it replaces the C library libintl.h by its own, which does #define gettext libintl_gettext. Then, when packages want to use gettext, autoconf realize that gettext is available in the C library and therefore do not add -lintl to the LDFLAGS, causing the build failure because the program has been compiled to use libintl_gettext but this function is not available. Therefore, we should only use gettext if a uClibc internal toolchain or a uClibc external toolchain. If an external glibc toolchain is used, gettext shouldn't be used. In order to implement that, we introduce the BR2_NEEDS_GETTEXT option, which is hidden to the user, and whose value is computed automatically from the rest of the configuration.
