[uClibc]Patch to fix globfree()

[Norman Shulman]

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.
