 Log Message:
 PR pkg/48890 was proposed. Thanks. But this commit is slightly
 different from the PR (When submitting patch to pkgsrc with
 adding more patches, submitter should do cvs add
 patches/patch-hoge, before creating the pkgsrc patch, thanks).
 
 I belive both simulavr and avr-libc will be packaged fine with this.

 4.7.3 to 4.8.3  -- From grepping 'avr' from NEWS file:
 --------------
    On AVR, the configure option --with-avrlibc supported since GCC 4.7.2
    is turned on per default for all non-RTEMS configurations. This option
    arranges for a better integration of [3]AVR Libc with avr-gcc. For
    technical details, see [4]PR54461. To turn off the option in non-RTEMS
    configurations, use --with-avrlibc=no. If the compiler is configured
    for RTEMS, the option is always turned off.
 
      * Support has been added for the AVR-specific configure option
        --with-avrlibc=yes in order to arrange for better integration of
        [3]AVR-Libc. This configure option is supported in avr-gcc 4.7.2
        and newer and will only take effect in non-RTEMS configurations. If
        avr-gcc is configured for RTEMS, the option will be ignored which
        is the same as specifying --with-avrlibc=no. See [4]PR54461 for
        more technical details.

 (Picking up AVR related topic from above info):
 The AVR port's libgcc has been improved and its multilib
 structure has been enhanced. As a result, all objects
 contributing to an application must either be compiled with
 GCC versions up to 4.6.x or with GCC versions 4.7.1 or
 later. If the compiler is used with AVR Libc, you need a
 version that supports the new layout, i.e. implements #35407.
 
 The AVR port's -mshort-calls command-line option has been
 deprecated. It will be removed in the GCC 4.8 release. See
 -mrelax for a replacement.
 
 The AVR port only references startup code that clears .bss and
 the common section resp. initializes the .data and .rodata
 section provided respective sections (or subsections thereof)
 are not empty, see PR18145.
   Applications that put all static storage objects into
 non-standard sections and / or define all static storage
 objects in assembler modules, must reference __do_clear_bss
 resp. __do_copy_data by hand or undefine the symbol(s) by
 means of -Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.
