b859f2750b libc/math: fix log and logf calculations on ARMv7 (and maybe others)
Probably this is a bug of a GCC, but on AMRv7 the code "if (relax_factor > 1)"
generates "bne.n" instruction if "relax_factor" is "int". Few lines above
"relax_factor *= LOG_RELAX_MULTIPLIER;" is done without overflow check hence
at some moment overflow occurs and "relax_factor" becomes a zero and condition
"if (relax_factor > 1)" becomes always evaluated to "true" hence "epsilon"
becomes zero always.

Probably this is not the best way to fix the bug (The best way is to report it
to GCC), but this change allows to get correct behavior of "log" and "logf" for
ARMv7 based MCUs

2e80d5e38e libs/libc/math: Fix calculation error of log function
Fix a problem where the log function would loop infinitely by
calculation error when a specific value was passed. For example,
in the following case, the log function loops infinitely and
never returns. So, this commit fixes to return the right value.

  double a = 7883961.5;
  double b = log(a);

dc8c814ca3 Squashed commit of the following:
Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

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.
