On Master All GDB Builds Fail on Cygwin

[Joel Sherrill]

Hi

I left a build going yesterday on Cygwin and GDB failed with this for every
architecture. I updated my Cygwin install this morning and it still fails
with this:

cp-support.o:/home/jrs007/rtems-cron-6/rtems-source-builder/rtems/build/arm-rtems6-gdb-0295dde-x86_64-pc-cygwin-1/build/gdb/../../sourceware-mirror-binutils-gdb-0295dde/gdb/psymtab.h:32:(.text+0x5291):
relocation truncated to fit: R_X86_64_PC32 against undefined symbol `TLS
init function for thread_local_segv_handler'
cp-support.o:/home/jrs007/rtems-cron-6/rtems-source-builder/rtems/build/arm-rtems6-gdb-0295dde-x86_64-pc-cygwin-1/build/gdb/../../sourceware-mirror-binutils-gdb-0295dde/gdb/psymtab.h:32:(.text+0x529b):
relocation truncated to fit: R_X86_64_PC32 against undefined symbol `TLS

collect2: error: ld returned 1 exit status

'/home/jrs007/rtems-cron-6/rtems-source-builder/rtems/build/arm-rtems6-gdb-0295dde-x86_64-pc-cygwin-1/build/gdb'

I found that there are others with the same problem. The only one with a
patch was this:

https://stackoverflow.com/questions/61984974/failed-to-build-avr-and-arm-gdb-9-1-under-cygwin-relocation-truncated-to-fit

I know Cygwin is way down folks' list but any ideas?

Thanks.
