make: rename CFLAGS in target Makefiles to TGT_CFLAGS

Browse Source 
Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.

Added information in README.md about existence and usage of CFLAGS
environment variable in build process.

* `CFLAGS` - Add to or supersede compiler flags
If the library needs to be compiled with additional flags, they can be
passed to the build system via the environment variable `CFLAGS`. The
contents of `CFLAGS` will be placed after all flags defined by the build
system, giving the user a way to override any default if necessary.
Examples:
$ CFLAGS="-fshort-wchar" make # compile lib with 2 byte wide wchar_t
