Add a testcase to check alignment of PT_LOAD segment [BZ #28676]

|

commit 718fdd87b1b98ef88e883a37d9c18867256fa5a4

elf: Properly align PT_LOAD segments [BZ #28676]
|
||||
|
||||
When PT_LOAD segment alignment > the page size, allocate enough space to
|
||||
ensure that the segment can be properly aligned. This change helps code
|
||||
segments use huge pages become simple and available.
|
||||
|
||||
This fixes [BZ #28676].
