[OE-core] [CONSOLIDATED PULL 16/30] cpan.bbclass: Fix CCFLAGS.

[Saul Wold]

From: Xin Ouyang <Xin.Ouyang at windriver.com>

We should not just replace CCFLAGS with CFLAGS while compiling, because
this may cause run-time errors with perl's DynaLoader.pm.

Tested on qemux86 with new libnet-libidn-perl bb recipe:

root at qemux86:~# perl -e "use Net::LibIDN"
Not a CODE reference at /usr/lib/perl/5.14.2//DynaLoader.pm line 213.
END failed--call queue aborted at /usr/lib/perl/vendor_perl/5.14.2//Net/LibIDN.pm line 213.
Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
