glibc; perl; carme

[Elan Ruusamäe]

can't build things on carme due glibc 2.26, arekm please downgrade as 
was done on builders

and therefore can't build other things like ImageMagick, php, ...


also the perl from builders seems broken, obsoletes itself:



poldek:/all-avail> ins perl-devel

could it be from this commit?
