Dirk Neukirchen d2d4fe2cbe grub2: disable liblzma dependency
Florian Ekert reported:

"I have build a fresh master branch recently, Since your last change [1]
on grub2, I have now a new dependency on liblzma for the install package
grub2-editenv.

root@st-dev-07 /usr/lib # ldd /root/grub-editenv
       /lib/ld-musl-x86_64.so.1 (0x7f684b088000)
       liblzma.so.5 => /usr/lib/liblzma.so.5 (0x7f684b06d000)
       libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x7f684b059000)
       libc.so => /lib/ld-musl-x86_64.so.1 (0x7f684b088000)

This was not the case before your update.

root@st-dev-07 /usr/sbin # ldd /usr/sbin/grub-editenv
       /lib/ld-musl-x86_64.so.1 (0x7fd970176000)
       libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x7fd970162000)
       libc.so => /lib/ld-musl-x86_64.so.1 (0x7fd970176000)

My build complains that it cannot satisfy the runtime package dependency
for grub2-editenv.

If I add the following changes to the package all works as expected.

+  DEPENDS:=@TARGET_x86 +liblzma
  VARIANT:=pc

This is a hotfix but I dont´t think this is the final solution, because lzma is provided by the package xz.
And This is maintained in the package feed [not the core]"

Dirk stated & offered his patch to disable liblzma and thus resolve the
'out of core dependency' problem:

"LZMA is used in mkimage.c
disabling it prints
Without liblzma (no support for XZ-compressed mips images) (explicitly disabled)
(see configure.ac)

liblzma is autodetected so this issue was present but hidden somehow

[unsure: grep/image generation does not use grub with that option]
OpenWrt does not use that feature currently

[!] some scripts and examples use --compression=xz or -C xz and those will break

grub has an internal xzlib for different "lzma" functionality
(ext. LIBLZMA from XZ (GRUB_COMPRESSION_XZ) vs. GRUB_COMPRESSION_LZMA)"

Hopefully fixes e74d81ece2 and doesn't
break anything else.
