The only reason is to test it without ifuncs. Musl libc unlike glibc does not
have ifunc support. Why because it is supposed to be an "embedded" libc but I
am not sure if that is not a good reason not support ifuncs really because I
can see an use case between 2 different generations of SoCs using the same
rootfs to run an application and such.
