 Problem: something like ecryptfs-utils, which needs the gettext program at
runtime...

 This one could perhaps be solved by adding a BR2_HAS_GNU_GETTEXT. But again, of
course, it must be possible to select gettext in that case.

 That sounds like a bad idea. What's the point of using musl if you're going to
add a bunch of GNU extensions to it?


 Another option is that we add a different flag to indicate the dependency on
libintl:

config BR2_PACKAGE_GETTEXT_WITH_LIBINTL
	bool
	default y
	depends on BR2_PACKAGE_GETTEXT
	depends on BR2_STATIC_LIBS
	depends on !BR2_TOOLCHAIN_USES_GLIBC


 HTTPING_LDFLAGS = $(TARGET_LDFLAGS) \
        $(if $(BR2_PACKAGE_GETTEXT_WITH_LIBINTL),-lintl) \


 There's just about 30 packages that ned to be adapted.
