fixed fixdep permission denied problem by removing '-B'(build all targets unconditionally) option from make

- initramfs lags 1 build behind but it only affect the kernel modules which
  we don't have in initramfs - it's only used for NAND flash boot
  to mount overlayfs and switch_root there

changing DEFAULTTUNE to match one in the Xilinx's layer helped with Kernel Oops - it set -mfloat-abi from 'softfp' to 'hard'

* capital Ms
* commeted out line with parameters
* sometime it does not like it in Kconfig:
  when 'tristate' is not followed by a comment as for CONFIG_MTD_NAND_OTP it should be:
  config CONFIG_MTD_NAND_OTP
    tristate "some description"
    default n

2. + '-ldl' to CFLAGS
