In fact the reason why you can only use glibc is two-fold:

 * You select elfutils, and elfutils does not build on musl.

 * uftrace uses ADDR_NO_RANDOMIZE, which isn't supported in uClibc

So it would be good to write something like this:

	# elfutils not available for musl, uClibc-ng does not 
	# provide ADDR_NO_RANDOMIZE, so only glibc is supported
	depends on BR2_TOOLCHAIN_USES_GLIBC

Could you cut this line at ~80 characters, using a backslash ? See
other packages.

Could you use sha256 hashes instead ?

Please don't encode the "v" in the version field. So please do:

UFTRACE_VERSION = 0.9.4
UFTRACE_SITE = $(call github,namhyung,uftrace,v$(UFTRACE_VERSION))

Indeed, this will allow UFTRACE_VERSION to be used to check if new
uftrace releases are available, using release-monitoring.org.

BR2_PACKAGE_LUAJIT is never going to be "n", so this condition will
never be true. Also, if luajit *is* there, you want luajit to be
compiled before uftrace. So you want something like this:

# No --with-<option> available
ifeq ($(BR2_PACKAGE_LUAJIT),y)
UFTRACE_DEPENDENCIES += luajit
else
UFTRACE_CONF_OPTS += --without-libluajit
endif

> +ifeq ($(BR2_PACKAGE_NCURSES_WCHAR),n)

Same comment as above.

> +$(eval $(autotools-package))

This is not an autotools-based package: it uses a hand-written
configure script, not one that is generated by autoconf. For example,
this explains why it doesn't support --with-<foo>, but only
--without-<foo>.

So, please use the generic-package infrastructure in this sort of
cases. Using autotools-package should really only be done for packages
that do use autoconf.

Could you adjust your package according to this ?

Thanks a lot!

Thomas
