- Let julia build more own chosen deps:

libunwind, pcre2 and mpfr (not to use some more of the system libs,
as occurred arch system versions got out of sync against julia choice)

- make test  instead of  testall.
`make test` does currently the following bit less than the
preceding command in check() correspondent to `make testall`
           LibGit2/online
           Pkg
the difference is given by the argument `default` or `all` to runtests.jl
See diff <(make -n test) <(make -n testall)
then add argument --help-list at the invocation of runtests.jl
to list and compare the tests run by `default` or `all` flavor
consider running some `make` command with -j1 argument in low memory
machines (the minimum seems to be in the order of 12Gb+ of available
memory and 20Gb of Swap)

- while testing this change the failure of test for
pcre2 and mpfr is just due to a version-string comparison,
	'pcre2=10.36.0' current system version would be 10.39
	'mpfr=4.1.0' a string version check refuses current version 4.1.0-p13
I let julia build internally such libraries too
the official changes description of pcre are in
https://github.com/PhilipHazel/pcre2/blob/master/ChangeLog
Also the attempt to prepare the deps source files with
`make full-source-dist` (now commented out) fails because
since at least November 4th 2020 the used url in pcre.mk,
ftp.pcre.org is "not anymore" online (as said in https://pcre.org)
I opened julia development issue https://github.com/JuliaLang/julia/issues/43895

- Remove an obsolete cp Make.user, because being specified in the
sources, an absolute symbolic link is created in src dir

- Removed a comment mentioning USE_SYSTEM_ARPACK, not anymore used

- Update dependency also with version range according to
https://github.com/JuliaLang/julia/blob/master/doc/src/devdocs/build/build.md#required-build-tools-and-external-libraries

if you have enough RAM there is chance that the build succeeds
