If CXX is exported to value like /usr/bin/g++ the ./configure fails to set HAVE_CXX and fails later on compile due to missing libutp

[samuli]

$ export CXX=/usr/bin/g++ $ ./configure

checking for /usr/bin/g++... no checking µTP... no

$ make

In file included from net.c:46:0: tr-utp.h:32:24: fatal error: libutp/utp.h: No such file or directory compilation terminated. make[1]: * [net.o] Error 1

Downstream bug report is:

I'm unsure of correct patch for this, and just dropped the broken check:
