Log: Put each rawdata object in a separate ELF section, so that each
can be aligned to a page boundary
Example:
pct_RAWDATA = ../fuse_app/fuse_app
pct_RAWDATA2 = ../libpmi/portals_client
pct_RAWDATA3 = ../libpmi/portals_server

CC_LDFLAGS += -Wl,--section-start -Wl,.rawdata=0x1000000
-Wl,--section-start -Wl,.rawdata2=0x1200000 -Wl,--section-start
-Wl,.rawdata3=0x1400000
