[PATCH v2 1/3] tools/nolibc: cast default values of program_invocation_name

[Thomas Weißschuh]

With -Wwrite-strings the plain assignment triggers a warning as a
'const char *' is assigned to a 'char *', removing the const qualifier.

Casting the const away is fine, as there is no valid modification that
can be done to an empty string anyways.
