arm/179561: Compilation issue for lighttpd on raspberry pi

[Sreekanth Rupavatharam]

Switching to g++ in make.conf caused it to fail with the following error.

>/  ===>  Building for pcre-8.32
/>/  make  all-am
/>/   CCLD   pcretest
/>/  ./.libs/libpcre.so: undefined reference to `__clear_cache'
/>/  cc: error: linker command failed with exit code 1 (use -v to see invocation)/


Then  I tried Rev r245446(Based on the discussion here 
http://lists.freebsd.org/pipermail/freebsd-arm/2013-January/004605.html 
and it seems to be not affected by the issue. Now I am able to build 
pcre natively on pi. I hope to try the same tree with cross-compilation 
today.
