gen-machine-conf fails if CONFIG_PRE_MIRROR_URL exactly matches default URL

[ph1l1p139]

Hi,

I'm using Petalinux 2023.1 but I suspect this issue applies to other versions too. If CONFIG_PRE_MIRROR_URL is set to the exact default URL of:

http://petalinux.xilinx.com/sswreleases/rel-v%s/downloads' % (plnx_major_ver)

(e.g "http://petalinux.xilinx.com/sswreleases/rel-v2023/downloads"

Then the petalinux-config command fails with a traceback as below:

[INFO] Generating plnxtool conf file

    mirrrs_string += 'SOURCE_MIRROR_URL = "%s"\n' % pre_mirror_url
UnboundLocalError: local variable 'mirrrs_string' referenced before assignment

Looking at xilinx_mirrors.py there is a typo in the variable mirrors_string (typed as mirrrs_string) on line 114.

I've found a workaround of adding a trailing / at the end of CONFIG_PRE_MIRROR_URL for now.

Thanks for the report. I'll fix the typo in the variable name.
