[OE-core] [PATCH 1/1] e2fsprogs: fix cross compilation problem

[Chen Qi]

When compiling e2fsprogs for qemumips64, we got compilation errors.
The root cause is that parse-types.sh script would fail for mips64.

However, the type size checking in parse-types.sh doesn't make much
sense in case of cross compilation. This is because that the typedef
statements in asm_types.h are for the target machine while the generated
binary in parse-types.sh script is executed on build machine.

This patch fixes such problem.

+Subject: e2fsprogs: fix cross compilation problem
+
+The checking of types in parse-types.sh doesn't make much sense in a
+cross-compilation environment, because the generated binary is executed
+on build machine.
+
+So even if asm_types.h has got correct statements for types, it's possible
+that the generated binary will report an error. Because these types are for
+the target machine.
