[Buildroot] [PATCH 1/4] boot/shim: fix build issue due to gnu-efi

[Thomas Petazzoni]

shim fails to build with:

console.c:448:5: error: ‘EFI_WARN_UNKOWN_GLYPH’ undeclared here (not in a function); did you mean ‘EFI_WARN_UNKNOWN_GLYPH’?
  448 |  {  EFI_WARN_UNKOWN_GLYPH,      L"Warning Unknown Glyph"},
      |     ^~~~~~~~~~~~~~~~~~~~~
      |     EFI_WARN_UNKNOWN_GLYPH
make[2]: *** [<builtin>: console.o] Error 1
make[2]: *** Waiting for unfinished jobs....

Backport upstream commit d230d02f990f02293736dca78b108f86c86d1bd0 to
resolve this issue.

+Subject: [PATCH] console: Fix a typo in the EFI warning list in gnu-efi
+
+Some versions of gnu-efi have a typo, in which "EFI_WARN_UNKNOWN_GLYPH"
+is accidentally "EFI_WARN_UNKOWN_GLYPH".  Work around that, so that we
+can use the not-silly one in console.c's list of error and warning
+messages.
+
+This is a backport from devel for:
+
+  commit 5f62b22ccd636d326b3229a2b196118701c6f3f7
