build_gcc_10 isl_tarfile wget

[Matthew Yu]

I was following your medium post for building gcc from source. Running the script build_gcc_10.sh led to a loopback connection failure upon the line (L174) __wget ftp://gcc/gnu.org/pub/gcc/infrastructure $isl_tarfile.

I was able to resolve this by swapping out ftp:// with https://.

Thanks for your hard work!

Thanks for this feedback, I will change the script to use https.
