This is blocking us from using gcc for guado-moblab.

CC=x86_64-cros-linux-gnu-gcc CXX=x86_64-cros-linux-gnu-g++ emerge-guado_moblab serf

configure: WARNING: openssl/opensslv.h:     section "Present But Cannot Be Compiled"
configure: WARNING: openssl/opensslv.h: proceeding with the compiler's result
checking for openssl/opensslv.h... no
configure: error: We require OpenSSL; try --with-openssl

This is because in the configure


Configuring Apache Portable Runtime library...

checking for APR... yes
  setting CPP to "x86_64-pc-linux-gnu-gcc -E"
  setting APR_LIBTOOL to "/build/guado_moblab/usr/share/build-1/libtool"
  adding "-pthread" to CFLAGS
  setting CPPFLAGS to " -DLINUX -D_REENTRANT -D_GNU_SOURCE"
  setting LTFLAGS to "--silent"


This is checking host compiler, since we set CC here, it uses the cros compiler instead of host compiler.
