[tex-live] Different behavior of options in mktexlsr (windows/linux)

[Pablo Alfonso González Luengo]

Hello everyone, when using the options "--version" and "--verbose" of
mktexlsr, the results are different in windows and in linux.
Here is an example of the outputs obtained
% win10 pro x64
C:\WINDOWS\system32>kpsewhich -var-value=TEXMFDBS
{!!C:/texlive/texmf-local,!!C:/texlive/2018/texmf-config,!!C:/texlive/2018/texmf-var,!!C:/texlive/2018/texmf-dist}

C:\WINDOWS\system32>mktexlsr --version
kpathsea version 6.3.0
mktexlsr: (C version 1.1 --ak 2002-2015)

C:\WINDOWS\system32>mktexlsr --verbose
kpathsea version 6.3.0
mktexlsr: (C version 1.1 --ak 2002-2015)

I was trying to see why when updating in windows (the same number of
packages) it takes almost four times what linux takes to run
"mktexlsr"
(I assume it's because of the file system used by windows 10).
