perl: Fix CCFLAGS on Perl 5.14.

A change to ExtUtils::CBuilder in Perl 5.14 causes CCFLAGS to
completely replace, rather than appending, the C flags.

The unfortunate consequence of this is that vital flags such as
-D_FILE_OFFSET_BITS=64 are missing.  For 32 bit code, this means you
get binary-incompatible code that completely fails to load.

For further analysis see:

http://www.nntp.perl.org/group/perl.perl5.porters/2011/04/msg171535.html

This commit changes CCFLAGS so that it appends to the existing
$Config{ccflags} instead of replacing it.  On earlier versions of Perl
this means we get two copies of the flags, which is unfortunate but
should be safe.

Also, ignore MYMETA.yml file produced by Perl 5.14.
