I cloned binutils-gdb repository from here (master branch) on a linux machine (Ubuntu) and I want to compile it for Windows (using x86_64_w64_mingw32 toolchain).
First, I ran ./configure with the following options to specify the cross-compile toolchain.
./configure --prefix=/usr/x86_64-w64-mingw32 --target=arm-none-eabi --host=x86_64-w64-mingw32
Then I ran make and get the following error (I omitted most of the output because it is pretty large):
[...]

I think it has something to do with time_t being typedef'd as a long long int (64 bit integer) in the host platform (Windows), however, the function os_time from the file sim/common/callback.c:414 (path relative to project root), takes a long (32 bit integer) as a parameter:
static long
os_time (host_callback *p, long *t)
{
return wrap (p, time (t));
}
How can I fix this error? Or are there any issue trackers for binutils-gdb?
This is because you are building the current, non-release,development version - I got the exact same error while building from the latest git revision at the time I cloned the repository, 0a703a4cedffa6f3824e87f115e8d392e32de191.
If you really want to build from the development tree, you will have to wait for the issue to be fixed, or to fix it by yourself - this is not being addressed in this answer.
But if building the latest released version, 2.36.1, is sufficient, the procedure hereafter will work (tested on Ubuntu 20.04 TLS):
wget https://ftp.gnu.org/gnu/binutils/binutils-2.36.1.tar.gz
tar zxf binutils-2.36.1.tar.gz
mkdir binutils
cd binutils
../binutils-2.36.1/configure --prefix=$(pwd)/binutils-2.36.1-x86_64-w64-mingw32 --target=arm-none-eabi --program-prefix=arm-none-eabi- --host=x86_64-w64-mingw32
make
make install
ll -gG binutils-2.36.1-x86_64-w64-mingw32/bin/

I did not test building from the git repository after having checked-out the binutils-2_36_1 tag:
git -C binutils-gdb checkout binutils-2_36_1
But it should work, if what was tagged is what was packaged in the archive file, which should be the case.
