    string: Use asm alias instead of symbol redirections for stpcpy and mempcpy
    
    Commit 939da411433 added symbols redirections to handle ISO C
    namespace, however some compiler does not support to redeclare the
    function prototype.  Moving these defintions to exported header
    it not a good practice (it exposes a internal implementation and
    it would require to add macros to define it only internally).
    
    Instead this patch replaces the symbol redirections by direct asm
    aliases, as done to handle libcall generation done by compiler on
    some loop optimizations. The only issue is sparc binutils generates
    an extra __mempcpy plt not called anywhere in the code, which indicates
    a binutils issue (this is added in the localplt.data for now).
    
    Checked on most of affected ABIs.

[glibc/azanella/clang] string: Use asm alias instead of symbol redirections for stpcpy and mempcpy

    string: Use asm alias instead of symbol redirections for stpcpy and mempcpy
    
    Commit 939da411433 added symbols redirections to handle ISO C
    namespace, however some compiler does not support to redeclare the
    function prototype.  Moving these defintions to exported header
    it not a good practice (it exposes a internal implementation and
    it would require to add macros to define it only internally).
    
    Instead this patch replaces the symbol redirections by direct asm
    aliases, as done to handle libcall generation done by compiler on
    some loop optimizations. The only issue is sparc binutils generates
    an extra __mempcpy plt not called anywhere in the code, which indicates
    a binutils issue (this is added in the localplt.data for now).
    
    Checked on most of affected ABIs.
