uClibc 0.9.19 has a bug in globfree(). If the previous call to
glob(...,pglob) used the GLOB_DOOFFS flag to reserve the first
pglob->gl_offs slots of pglob->gl_pathv, globfree(pglob) would attempt
to free the objects pointed to by those slots. If those objects were not
on the heap, the system would crash.
The attached patch fixes this.
