elf/dl-load.c: Use __strdup.
During a refactoring pass several repeated blocks of code in dl-load.c were turned into a call to a local function named local_strdup. There is no need for local_strdup, and the routines should instead call __strdup. This change does just that. We call the internal symbol __strdup because calling strdup is unsafe. The user might be using a standard that doesn't include strdup and may have defined this symbol in their application. During a static link we might reference the user defined symbol and crash if it doesn't implement a standards conforming strdup. The resulting code is simpler to understand, and makes it easier to debug. No regressions on x86_64. 2014-10-28 Carlos O'Donell <carlos@redhat.com> * dl-load.c (local_strdup): Remove. (expand_dynamic_string_token): Use __strdup. (decompose_rpath): Likewise. (_dl_map_object): Likewise.
