Consider changing linker on Linux from `ld.gold` to `ld`

[cameel]

@cameel Maybe an interesting side note. The resulting installation shrunk from 14.92 MiB to 14.33 MiB when switching from ld.gold to ld. Installation via https://aur.archlinux.org/packages/solidity. Considering the installation contains much documentation which was not affected by a change of the linker, the binaries must be the reason for all the size difference.

Gesamtgröße der installierten Pakete:  14,33 MiB
Größendifferenz der Aktualisierung:    -0,59 MiB
