Add llvm linker detection to configure
https://gcc.gnu.org/ml/gcc-patches/2018-10/msg01240.html
This is currently only used for webengine, where link time really matters.
New configure options:
* force 'lld' '-linker lld' or' --linker=lld'
* force 'gold' '-linker gold' or '--linker=gold'
* force 'bfd' '-linker bfd' or '--linker=bfd'
Note before by default gold was always forced (if supported) now default linker
is system default one.
[ChangeLog][Tools][configure & build system] Added --linker=[bfg,lld,gold] configure flag.
