anjiahao 7c96537a58 string:use builtin function to optimize libc function
This allows the compiler to automatically identify which string functions
can be compiled into libraries, and the compiler's internal implementation
is faster than libc functions.

raiden00pl 13ab107d67 libc: remove reference to non-existent readme
remove reference to non-existent readme in libc.

Pointing to the documentation page doesn't make sense in this case,
because it doesn't explain the use of `#undef XXX` for this case anyway.

mage1 def007e2d7 add #undef for some libc function
since it's useful to redirect these functions to others
sometime(e.g. validate the memory before write).

Gregory Nutt cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now.
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
