new [gcc] build failure and other questions #995

Now that Homebrew/linuxbrew-core#21380 is in (🎊!), I tried to reinstall gcc, but it's failing to build. Here's approximately what I did:

Start with linuxbrew with nonstandard prefix (many things have to build), and old gcc & gcc@5.
brew upgrade gcc Fails with compiler error.
Thinking existing gcc/gcc@5 are interfering, brew unlink those and retry brew upgrade gcc. Fails with same compiler error.
Thinking unlinking isn't enough, brew remove those (and [email protected] to finally resolve brew dr warning) and brew install gcc. Fails with different compiler error! Progress!
Okay, really clean house! brew remove a bunch of related formulae and other leaves and retry brew install gcc. Successfully (re)installs some dependencies, but gcc fails with differenter compiler error! Progress?

So question 1: How can I get gcc to install?

Question 2: Wait, what's with those dependencies from step 5??
==> Installing dependencies for gcc: [email protected], libmpc, glibc and gcc@5
[email protected], glibc, & gcc@5 aren't supposed to be required:

ad-user-ads-11 ~ ★ brew info gcc
...
==> Dependencies
Required: gmp ✔, isl ✔, libmpc ✔, mpfr ✔, zlib ✔, binutils ✔
...

ad-user-ads-11 ~ ★ brew deps --include-build gcc
binutils
gmp
isl
libmpc
m4
mpfr
zlib

Maybe I just don't understand something about brew's dependency model? I tried to investigate, but I don't see why step 5 did what it did. The full log of my flailing is here.
Edit: Dependency thing doesn't seem specific to gcc. brew upgrade gh also tried to install those three:
==> Installing dependencies for gh: [email protected], glibc and gcc@5

Edit: question 3: For the good of the order, does this represent any kind of problem with the gcc setup from Homebrew/linuxbrew-core#21380, that other users might experience when upgrading or installing?

What is your system compiler? Can you give us a copy of brew config?

In my experience our GCC formulae don't build with brewed glibc because during the bootstrap process one of the early compiler binaries ends up linking to the system glibc but uses the ld linker from brewed glibc. Since gcc is relocatable, the solution I've been using has just been to install gcc with brew install --force-bottle gcc.

For now I think we could manually add cellar: any to the gcc formulae, until we figure out how to make sure our relocation testing ignores the cellar references in the gcc binaries.

Yes, can you try brew install --force-bottle gcc please?

No, I have been doing this over the past 3 years and always forget to add it back. This needs to be fixed in brew's bottling code, once and for all.

It's a relocatable bottle? Then why the heck am I building it?
The gcc bottle seems to work, but it's still installing those extra dependencies. Also note “Please report this issue” near the bottom.
