We have been moving to build support libraries, such as GMP, separately and not
by links into the source tree of gcc. MacOS M silicon requires a specific option
for GMP to work and this has resulted in us building these libraries before
building the packages that depend on them because the upstream provide no means
to inject specific options. GDB added GMP and it seems more are being added so
we need to add support to build them before GDB and remove the symlink'ing into
the GCC source tree. The GMP change should provide a suitable template for doing
this.
