Nope.  Just turn:

.globl foo
foo:
...
     b foo

into

.globl foo
foo:
.Lfoo:
...
     b .Lfoo

No additional branches, no additional symbols, no differences in the
resulting object, and you're now clear that you really really mean to
branch to that symbol, and not to whatever symbol might override it.
