Some versions of GCC are known to suffer from a BTI code generation bug, meaning that CONFIG_CC_HAS_BRANCH_PROT_PAC_RET_BTI cannot be solely used to determine whether or not we can compile with kernel with BTI enabled. Update the BTI Kconfig entry to refer to the relevant GCC bugzilla entry (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94697) and update the check now that the fix has been merged into GCC release 10.1.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
