Initially I merely noticed the regression addressed by the 1st patch,
but looking more closely revealed further deficiencies. After having
moved the FIXME in patch 3 I couldn't resist and address that issue
at least partly (patch 4), seeing that three and a half years have
passed and nothing was done to improve the situation.

1: build: work around bash issue
2: build: correctly report non-empty section sizes upon .o -> .init.o conversion
3: build: also check for empty .bss.* in .o -> .init.o conversion
4: EFI: free unused boot mem in at least some cases
