Ash glob symlink regression when using libc glob

[Lauri Kasanen]

Hi,

It was reported the following case fails with bb 1.27.2:

ln -s nonexistent mylink
mv myli* someother

It also fails with master. I bisected it to
b3f29b452a660a7293162897424bed205f7f9147, "ash: use glob() from libc".
Works with bash.
