[PATCH] board: Synology: common: Fix typo in Makefile

[Phil Sutter]

Due to this, legacy.c was neither compiled nor linked into the binary
and thus booting legacy DS414 firmware failed. Missing atag setup led to
no console output (and probably stalled boot) after:

| Uncompressing Linux... done, booting the kernel.

Fixes: 9774462e34faa ("arm: Disable ATAGs support")
