build scripts work again.


BUILD/compile-pentium-max:
  Added "--with-embedded-server" to have the libmysqld files included
  in the source distribution when using "make dist"
Build-tools/Do-linux-build:
  Only use the "--with-other-libc" parameter, if another libc actually
  exists, since this will also force static linking, which does not work
  together with OpenSSL
Makefile.am:
  Removed hard-coded file name for TAR, let configure do this instead
  (many systems actually ship GNU tar installed as "tar" instead of
  "gtar")
configure.in:
  Added check for GNU tar named "gtar", fall back to "tar" if "gtar"
  was not found (and hope, that it's a GNU tar as well - this should
  probably be checked more properly)
include/Makefile.am:
  Added "my_semaphore.h" to pkginclude_HEADERS since it was missing
  from the distribution
strings/Makefile.am:
  Added "longlong2str.c" since it was missing from the distribution
support-files/mysql.server.sh:
  Added LSB-compatible header info to make init script more portable
support-files/mysql.spec.sh:
  - Use more RPM macros (e.g. infodir, mandir) to make the spec
    file more portable
  - reorganized the installation of documentation files: let RPM
    take care of this
  - reorganized the file list: actually install man pages along
    with the binaries of the respective subpackage
  - don't include libmysqld.a in the devel subpackage as well, if we
    have a special "embedded" subpackage
  - reworked the package descriptions
