[bug#49010] [PATCH core-updates] gnu: custom-gcc: Update regex for removing executables.

[Sarah Morgensen via Guix-patches via <guix-patches@gnu.org>]

Do not match "gccgo". Match "gcov-dump" and "gcov-tool", as well as
"lto-dump" (which was introduced in GCC 10).

* gnu/packages/gcc.scm (custom-gcc)[arguments]: Update regex used for
matching broken or conflicting executables.
