Question: module compilation failure with less number of files

Hi All,

I am trying to compile some ACPI tables, and I observed that
if I specify less minimal tables/asl as Sources for ACPI tables module INF
file
(resulting in less size of overall module), compilation fails with below
error:

build.py...
 : error F003: Output file for RAW section could not be found for
Platform/ARM/JunoPkg/AcpiTables/AcpiTables.inf

To reproduce this issue,
1) Apply below patch (just keeping Fadt.c here as example;
Other ways: just keep ASL file after removing some objects to reduce file
size; or keep combination of .c and .asl files - **as long as these files
are small**):
--------------------------------------------------------------------------------

2) Now compile the module:

build   -a AARCH64 -t GCC5 -p Platform/ARM/JunoPkg/ArmJuno.dsc -m

Can anyone help understand this behavior?
